VCC5

Active-Low, 5V CMOS Reset Output

Active-Low Reset Output. Open-drain for the

MAX6352/MAX6355/MAX6358, 5V push-pull for the

MAX6353/MAX6356/MAX6359, and 3V push-pull for

the MAX6354/MAX6357/MAX6360.

Ground

Manual-Reset Input. Pull low to force a reset. RST,

RST5, and RST3 remain active as long as MR is low

and for the timeout period after MR goes high.

Leave unconnected or connect to VCC5 if unused.

VMR must be below VCC5.

+3.3V/+3.0V Supply Input. Powers the device when

it is above VCC5 and monitors its own voltage.

Active-Low, 3V CMOS Reset Output

Undervoltage Reset Comparator Input. Asserts

reset when the monitored voltage falls below 1.23V.

Set the reset threshold with an external resistor-

divider. Connect to VCC5 if unused. VRSTIN must be

below VCC5.

Watchdog Input. If WDI remains either high or low

longer than the timeout period, then reset is trig-

gered. The timer clears when reset is asserted or

whenever WDI sees a rising or falling edge. Leave

floating to disable it if unused.

+5V Supply Input. Powers the device when it is

above VCC3 and monitors its own voltage.
