MAXIM MAX6832, MAX6840 User Manual

General Description

The MAX6832–MAX6840 are microprocessor (µP)
supervisory circuits used to monitor low-voltage power
supplies in µP and digital systems. They provide excel­lent circuit reliability and low cost by eliminating exter­nal components and adjustments when used with
+1.2V to +1.8V powered circuits.

These devices assert a reset signal whenever the V

CC

supply voltage declines below a preset threshold or
whenever manual reset (MR) is asserted. Reset remains
asserted for a fixed timeout delay after VCChas risen
above the reset threshold or when manual reset is
deasserted. Five different timeout periods are available:
70µs (voltage detector), 1.5ms, 30ms, 210ms, and 1.68s.
Reset thresholds suitable for operation with a variety of
supply voltages are available.

The MAX6832/MAX6835/MAX6838 have a push-pull
active-low reset output (RESET). The MAX6833/
MAX6836/MAX6839 have a push-pull active-high reset
output (RESET) and the MAX6834/MAX6837/MAX6840
have an open-drain active-low reset output (RESET). The
open-drain active-low reset output requires a pullup resis­tor that can be connected to a voltage higher than VCC.

The MAX6835/MAX6836/MAX6837 feature a debounced
manual reset input (MR), while the MAX6838/MAX6839/
MAX6840 provide a RESET-IN input allowing the user to
externally adjust the reset threshold. The reset compara­tor is designed to ignore fast transients on VCC.

Low supply current of 7.5µA makes the MAX6832–
MAX6840 ideal for use in portable equipment. These
devices are available in 3- and 4-pin SC70 packages.

MAX6832–MAX6840

Detailed Description

Reset Output

A microprocessor’s (µP’s) reset input starts the µP in a
known state. The MAX6832–MAX6840 assert a reset to
prevent code-execution errors during power-up, power­down, or brownout conditions. They also assert a reset
signal whenever the VCCsupply voltage falls below a
preset threshold (MAX6832–MAX6837) or RESET-IN
falls below the adjustable threshold (MAX6838/
MAX6839/MAX6840), keeping reset asserted for a fixed
timeout delay (Table 2) after VCCor RESET-IN has risen
above the reset threshold. The MAX6832/MAX6835/
MAX6838 use a push-pull active-low output, the
MAX6833/MAX6836/MAX6839 have a push-pull active­high output, and the MAX6834/MAX6837/MAX6840
have an open-drain active-low output stage. Connect a
pullup resistor on the MAX6834/MAX6837/MAX6840’s
RESET output to any supply between 0 and 6V.

Manual Reset Input

Many µP-based systems require manual reset capabili­ty, allowing the operator, a test technician, or external
logic circuitry to initiate a reset. Reset remains asserted
while MR is low, and for a fixed timeout delay after MR
returns high. This input has an internal 20kΩ pullup
resistor, so it can be left open if it is not used. MR can
be driven with CMOS logic level, or with open-drain/col­lector outputs. To create a manual reset function, con­nect a normally open momentary switch from MR to
ground; external debounce circuitry is not required. If

MR is driven from long cables or if the device is used in
a noisy environment, connecting a 0.1µF capacitor from
MR to ground provides additional noise immunity.

RESET-IN Information

The MAX6838/MAX6839/MAX6840 feature a RESET-IN
input for monitoring supply voltages down to 0.44V. An
external resistive-divider network can be used to set
voltage monitoring thresholds as shown in Figure 1. As
the monitored voltage falls, the voltage at RESET-IN
decreases and asserts a reset when it falls below the
RESET-IN threshold (V

RSTIN

). The low-leakage current

at RESET-IN allows for relatively large-value resistors to
be used, which reduce power consumption. For exam­ple, for a 0.6V monitored trip level, if R2 = 200kΩ, then
R1 = 70.3kΩ. Note that the minimum VCCof 1.1V is
required to guarantee the RESET-IN threshold accura­cy (see Electrical Characteristics table).

Applications Information

Negative-Going VCCTransients

In addition to issuing a reset to the µP during power-up,
power-down, and brownout conditions, the MAX6832–
MAX6840 are relatively immune to short-duration nega­tive-going VCCtransients (glitches).

Figure 2 shows typical transient duration vs. reset com­parator overdrive, for which the MAX6832–MAX6840 do
not generate a reset pulse. The graph was generated
using a negative-going pulse applied to VCC, starting

0.1V above the actual reset threshold and ending
below it by the magnitude indicated (reset comparator
overdrive). The graph indicates the maximum pulse
width a negative-going VCCtransient can have without
causing a reset pulse. As the magnitude of the tran­sient increases (goes farther below the reset threshold),
the maximum allowable pulse width decreases. A 0.1µF
bypass capacitor mounted as close as possible to the
VCCpin provides additional transient immunity.

Ensuring a Valid Reset Output

Down to V

CC

= 0

When VCCfalls below 0.55V, the MAX6832/MAX6835/
MAX6838 push-pull RESET output no longer sinks cur­rent—it becomes an open circuit. Therefore, high­impedance CMOS logic inputs connected to RESET

can drift to undetermined voltages. This presents no
problem in most applications since most µP and other
circuitry are inoperative with V

CC

lower than 0.55V.

However, in applications where RESET must be valid
down to 0, adding a pulldown resistor to RESET causes
any stray leakage currents to flow to ground, holding
RESET low (Figure 3). R3’s value is not critical; 100kΩ
is large enough not to load RESET and small enough to
pull RESET to ground.

A 100kΩ pullup resistor to VCCis also recommended
for the MAX6833/MAX6836/MAX6839 if RESET is
required to remain valid for VCC< 0.85V.

Interfacing to µPs with Bidirectional

Reset Pins

Since the RESET output on the MAX6834/MAX6837/
MAX6840 is open-drain, these devices interface easily
with µPs that have bidirectional reset pins. Connecting
the µP supervisor’s RESET output directly to the µP’s
RESET pin with a single pullup resistor allows either
device to assert a reset (Figure 4).

Output

with Multiple Supplies

Generally, the pullup connected to the MAX6834/
MAX6837/MAX6840 will connect to the supply voltage
that is being monitored at the IC’s VCCpin. However,
some systems may use the open-drain output to level­shift from the monitored supply to reset circuitry pow­ered by some other supply (Figure 5). Note that as the
MAX6834/MAX6837/MAX6840’s VCCdecreases, so
does the IC’s ability to sink current at RESET. Also, with
any pullup, RESET will be pulled high as V

CC

declines
toward 0. The voltage where this occurs depends on
the pullup resistor value and the voltage to which it is
connected.
