4. Interface Application

4.1 Power Supply

For non-battery applications, if the DC input voltage is +5V and users do not care about the power efficiency, a
high-current low-dropout regulator is recommended. The reference design is shown in Figure 5

Figure 5: LDO power supply reference circuit

Note: To ensure a proper behavior of the regulator under light load, an extra minimum load (R103 in Figure 5)
is required, because the current SIM5800 consumed is very small in sleep mode and power off mode. For more
details about minimum load, please refer to specification of MIC29302.

To increase power efficiency, the switching mode DC-DC converter is preferable, especially when DC input
voltage is quite high. The reference design is show in Figure 6, and it is recommended to reserve a proper ferrite
bead (FB101 in Figure 6) in series for EMI suppression.

Figure 6: DC-DC power supply reference circuit

The user can directly power the module with a single lithium battery or use other types of battery, but it should be
noted that its maximum voltage cannot exceed the maximum allowable voltage of the module, otherwise the
module will be damaged.

Note: The module supports charging function. When users use non-rechargeable power supply, they need to
turn off the charging function in the software or connect schottky diodes in the VBAT path to prevent reverse
flow of current into the power supply.

No matter which power supply design is adopted, please refer to the following figure for the design of VBAT pin
of the module.

Figure 7: VBAT Input reference circuit

In the Figure 7, C101/C105 is 100uF tantalum capacitors of low ESR; 33pF capacitance can effectively remove
high frequency interference; 5.1V/500mW zener diode can prevent the damage of surge on the chip. The
capacitance and zener diodes should be as close to the VBAT pin of the module as possible during PCB layout.

Table 3: Recommended Zener diode model

4.1.1 Power Supply Pins

The VBAT pins are used for power input, and pin 143, 144, 147, 148 should be connected to the power GND.
VRTC pin is the power supply of the RTC circuit in the module.

When designing the power supply in users’ application, pay more attention to the power losses. Ensure that the
input voltage never drop below 2.9V even when current consumption rises to 2A in the transmit burst. If the
power voltage drops below 2.9V, the module may be shut down automatically. The PCB traces from the VBAT
pins to the power supply must be wide enough to decrease voltage drops in the transmit burst. The power IC and
the bypass capacitor should be placed to the module as close as possible.

Figure 8: The minimal VBAT voltage requirement at VBAT drop

4.2 Power on/off

Do not open the module when the temperature and voltage limit of the module is exceeded. The module will be
shut down as soon as it detects these inappropriate conditions. In extreme cases such an operation can result in
permanent damage to the module.

SIM5800 also have a RESET pin used to reset the module. This function is used as an emergency reset. Users can
pull the RESET pin to the ground, and then the module will restart.

Figure 12: Reset circuit

Note: This function requires software modification. Please contact SIMCom.
The typical value of RESET pin high level is 1.8V, so for the 3V or 3.3V condition, customer could not directly

use MCU’s GPIO to driver this pin directly, refer to the following table for RESET hardware parameters.

Table 4: Electronic characteristic of the RESET Pin

4.3 VRTC

VRTC is the power supply for RTC circuit and charger output for coin cell or backup battery. If RTC support is
needed when the battery is removed, a qualified coin cell or keep-alive capacitor is required on the VRTC pin.
When VBAT is present and valid, coin cell charging is enabled through software control and powered from VBAT.

The connection circuit diagram is recommended as follows:

Customers can download and upgrade software via USB. The module provides a convenient way to download.
Customers do not need to connect VBAT, only insert USB cable to complete the download. In the download stage,
VBAT of the module can be provided by VCHG, but the current limit of this channel is very small, only enough
for the module to download, and the module cannot be started up through VCHG power supply.

The customer first run the download tool, and then inserts the USB. After the module detects the USB insertion, it
will automatically boot into the download mode. The connection diagram is as follows:

1. In the download phase, the current limit is very small from the VCHG to the VBAT path , only

enough for the module to download the required current. Therefore, normal startup function of
the module cannot be realized through VBUS power supply.

2. If there are other chips in the module VBAT network which will consume the current when the

power on, if the current consumption is high, it will also cause the module download failure.

4.5.1USB HOST

The SIM5800 module can provide the function of USB HOST, but the module does not have the output of 5V
power supply. Therefore, when using this function, the customer needs the external circuit to add 5V output.

The detection order of USB_HOST is as follows: when the device is connected, an interrupt signal is generated by
USB_ID first, then the software controls GPIO to enable external +5V output, and finally the data on
USB_DP/DM is detected. The recommended circuit diagram is as follows:

Figure 18:USB_OTG diagram

4.6 Charge management

The SIM5800 supports the charging function, and users can charge the lithium battery through the VBUS pin. The
maximum charging current can be supported up to 1A (TBD).

SIM5800_Hardware Design_V1.01 28 2018-10-08

Smart Machine Smart Decision

Figure 19: Charge diagram

Note: The standard charger supported by SIM5800 module needs to connect USB_DP and USB_DM
together, and the charging current can only reach the normal value set by the software after the software
determines that it is a standard charger. If there is no short connection between USB_DP and USB_DM,
the software thinks that it is a non-standard charger with a small charging current and a slow charging.

4.6.1Charger detection

When the VBUS pin voltage is higher than 4.3v (TBD), a hardware interrupt will occur inside the module. The
software recognizes whether the charger is inserted or the USB data cable is inserted by judging the state of
USB_DP/USB_DM.

Whenever an invalid charging source is detected (>7.0V),the charger detector will stop charging process
immediately to avoid burning out the chip or module. Furthermore, if the charger-in level is not high enough
(<4.3V),the charger will also be disabled to avoid improper charging behavior.

4.6.2Charging Control

When the charger is active, the charger controller will manage the charging phase according to the battery status.
During the charging period, the battery voltage is constantly monitored. The battery charger supports pre-charge
mode (VBAT<3.2V, PMIC power-off state), CC mode (constant current mode or fast charging mode at the range
of 3.2V<VBAT<4.2V) and CV mode (constant voltage mode) to optimize the charging procedure for Li-ion
battery.

4.6.2.1 Pre-charge mode

When the battery voltage is in the UVLO state, the charger will operate in the pre-charge mode. There are two
steps in this mode. While the battery voltage is deeply discharged below 2.2V,the trickle charging current is
applied to the battery, the trickle charging current is about 550ms pulse 70mA current when VBAT is under

2.2V.when the battery voltage exceeds 2.2V,the charging current is 300mA(AC charger) or 70mA(USB host).

4.6.2.2 Constant current mode

As the battery is charged up and over 3.3V,it can switch to the CC mode, In the CC mode charging current can be
set by registers up to 1A.for more details of the register, please refer to related software document.

4.6.2.3 Constant voltage mode

While the battery voltage reaches about 4.1V, a constant voltage is used for charging. The charging current is
gradually decreased step-by-step. The charging process is completed once the current reaches zero automatically.
Whenever the battery voltage exceeds 4.3V (programmed by SW),a hardware OV protection is activated and turns
off the charger immediately.

4.6.2.4 BAT_ID

SIM5800 provide the battery temperature monitoring function with Pin134 BAT_ID. It needs a 10K Ohm NTC
resistor , and connect to BAT_ID. In the charging procedure, the voltage on the BAT_ID will be a notice for the
temperature ,if the temperature is too high or too low, it will stop charging immediately to prevent from battery
damage. The battery connection is as following.

If customers to use the battery without thermistor, only connect VBAT and GND, at this time in order to prevent
the system determine the battery temperature anomaly, lead to cannot charge even unbootable, customers should
connect BAT_ID pin to GND via 10KR, so that we can make the system think battery temperature within the
scope of the work, system can normal boot and charging. However, this connection SIMCom is not recommended
for customers considering abnormal battery temperature.

SIM5800 provides three antenna interfaces including MAIN antenna, GNSS antenna, and WiFi/BT antenna. To
ensure good RF performance, users should meet the following requirements:

● Keep the RF traces at 50Ω.

● Maintain a complete and continuous reference ground plane from antenna pin to the RF connector.

● The RF traces should be away from any other noisy traces.

● Keep the RF traces as short as possible.

5. PCB Layout Guide

Usually, most electronic products with good performance are based on good PCB layout. A bad PCB layout will
lead to lots of issues, like TDD noise, SIM card can not be detected, etc. The final solution for these problems is to
redo PCB layout. Making good PCB layout at beginning will save development schedule and cost as well.

This section as below will give some guidelines on PCB layout.

5.1 Stack-up Options

At least, 4-layer through-hole PCB should be chosen for good impedance control and signal shielding.

5.2 PCB Layout

Key points to note in the PCB layout phase:

5.2.1 RF Trace

 RF connector should be placed close to the module’s antenna pin.
 Antenna matching circuit should be placed close to the antenna.
 Keep the RF traces at 50Ω.
 Maintain a complete and continuous reference ground plane from antenna pin to the RF connector.
 The RF traces should be far away from any other noisy traces.
 Keep the RF traces as short as possible.
 If using a coaxial RF cable to connect the antenna, please avoid spanning on UIM cards, power circuits and

high-speed digital circuits to minimize the impact of each other.

5.2.2 POWER/GND

 Both VBAT and return path should be as short and wide as possible .

6.8 Electro-Static Discharge

Electrostatic discharge (ESD) occurs naturally in laboratory and factory environments. An established
high-voltage potential is always at risk of discharging to a lower potential. If this discharge path is through a
semiconductor device, it may result in destructive damage.

SIM5800 must be handled according to the ESD Association standard: ANSI/ESD S20.20-1999, Protection of
Electrical and Electronic Parts, Assemblies, and Equipment.
