1 Introduction
The MC13713 Integrat ed Power Manage ment and Audi o Circuit is part of the chip set for Motoro la ’s 2.5G
Innovative Convergence™ (i.250) platform. This chipset also includes the MC13712 Dual-Band GPRS
Front End Integrated Circuit (IC), MMM6010/6011 Dual-Band GPRS Power Amplifier Module,
DSP56621 Baseband Processor, and the MC13715 Charge Control and Protection Circuit. This IC is
primarily targeted for the GSM/GPRS market but can be used in other systems with additional supporting
circuitry. In general, the architecture has been optimized to reduce cost for GSM/GPRS and additional
functionality to support other pr otocol s has not been in cluded . The MC13 713 is opti mized fo r use with the
other ICs in the platform, but can be used in other IC architectures.
The IC contains the necessary glue components of a modern GSM/GPRS cellular phone. The MC13713
integrates control logic, voltage regulators and converters, reference oscillator, charger interface, trimmed
bandgap reference, alert amplifier, speaker amplifier, microphone amplifier and bias generator, voltage
multiplier, and analog- to-digital converter multip lexer (MUX) on a single IC.

3.1 Voltage Reference (REF_REG)
The reference re gulator ( REF_REG) pro vides the 1.575 V refe rence vol tage f or all o ther volt age regul ators
on the MC13713 and can also source up to 200 µA to an external load. It is always turned on, even when
the MC13713 is off or in standby. These features are provided to maintain the Real Time Clock (RTC)
Oscillator on the MC13713 and the RTC registers on DSP56621.
REF_REG operates directly from B+. Regulation is guaranteed for a B+ voltage of 1.9 to 4.5 V, although
current sourcing capa bili ty falls off for B+ lower than 2.8 V. Bel ow 1.9 V, regulati on is not guara nteed bu t
current is available to a B+ as low as 1.3 V.
A low ESR bypass capacitor is required for noise reduction. Since this line is the reference for the rest of
the IC, external circuitry connected to this line should not be permitted to pull the voltage above or below
the limits in the specification, or to degrade the rise time on that contact. In the event B+ is removed, or
falls below the voltage at the REF_REG output, RTC clock circuitry internal to MC13713 and connected
to this contact will draw 25 µA. Additionally a discharge path exists through the regulator to B+, this will
typically be a non-guaranteed 2 k
A simplified block diagram of the circuit is shown in Figure 3.

All regulators are current limited. When the output load current approaches the regulator current limit the
output voltage will drop as necess ary to pr event the outpu t current from excee din g the maximum spe cified
current limit. All regulators require a low ESR tantalum or ceramic bypass capacitor on the output. If
capacitor values outside the range listed in the specified conditions are used, the IC may not meet the
specified requirement. This could be especially true for shutdown time, turn on time, overshoot, transient
response, and PSRR.
All regulators (with the exception of the voltage multiplier) are powered from B+. Table 6 lists the
electrical speci fications for the RF, I O, AUD, DIG, SIM, an d VIB regula tors. Unless oth erwise noted, each
specification refers to all regulators. While the regulators are quite similar, each regulator is intended for a

1. Unless noted, specification refers to all regulators.
The SIM regulator ( SIM_REG) i s the only regul ator that is progra mmable f or vo ltage . I ts ba sic topolo gy is
as shown in Figure 4 on page 9, but the divider resistors are implemented with switc habl e val ue s, sel ect ed
via an SPI command. In addition to an SPI enable bit, SIM_REG has a separate enable contact, SIM_EN.
This input can be used with the SIM car d soc ket to sh ut down voltage to the SIM card during removal and
insertion. This regulator can tolerate a short circuit on its output. When set to 2.85 V, the SIM regulator
will supply the 2.7 V needed for 3 V SIM card function even with an input voltage of 3.0 V, although
regulation and PSRR may be out of specification. 5 V SIM cards are not supported.
VM_REG regulates the output of the voltage multiplier (VMULT) described in Section 3.5. Its input is
internally wired to the output of VMULT, and their enable bits are common. The regulated 4.7 V voltage
can be used to power the synthesizer charge pumps, RF switches, or other high voltage requirements. The
voltage multiplier a nd r egulator are not inte nde d t o ha ve a high current output; 5 mA is the maximum they
can source.
The RF and audio regulators (RF_REG, AUD_REG) are separate from the other 2.775 V regulator,
(IO_REG), for noise isolation. Switching digital circuits should not be connected to those outputs. They
are separately enabled to allow for the independent timing needs of RF versus audio circuitry on a phone.
The vibrator regulator (VIB_REG) is intended only to be used to power the vibrator motor alert and is not
guaranteed to be stable with no load.
3.3 Analog Ground Generator, VAG
Another on-chip regulator that is not listed in the specifications is the Analog Ground Generator (VAG).
Shown in simplified block diagram form in Figure 5, this regulator is only used to generate the on-chip
virtual ground, at 1.325 V ± 100 mV, for the TX and RX audio paths and amplifiers. Two pins, VAG and
VAG_REF, are brought out for noise-reduction capacitors (0.01 to 0.1 µF, 15% tolerance, is required for
stable operation), because this ground must have very low noise and high supply rejection. VAG is not
intended to source curren t to external loads.

The divider resistors on Vref are disconnected to reduce current drain when the audio paths are not
enabled.
3.4 Backlight Current Source (BL_CURR)
The Backlight Current Source, BL_CURR, is intended to supply a constant current sink for use by back
light LEDs. The constant current is achieved by forcing a constant voltage across a resistor RBL.
Tolerance of this resistor must be considered when designing for specific re qui re me nt s. Tab le 7 shows the
BL_FB voltages and nomi nal o utp ut current of the block (IRBL) assuming RBL = 2.2
