Pin Description

FUNCTION

Active-Low, CMOS Reset Output Referenced to VCC1

Active-Low Reset Output. Open drain for the MAX6352/

MAX6355/MAX6358, push-pull with respect to VCC1 for

the MAX6353/MAX6356/MAX6359, and push-pull with

respect to VCC2 for the MAX6354/MAX6357/MAX6360.

Ground

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

RST1, and RST2 remain active as long as MR is low

and for the timeout period after MR goes high.

Leave unconnected or connect to VCC1 if unused.

VMR must not exceed VCC1.

Supply Input. Powers the device when it is above

VCC1 and monitors its own voltage.

Active-Low, CMOS Reset Output Referenced to VCC2

Undervoltage Reset Comparator Input. Asserts

reset when the monitored voltage falls below 1.22V.

Set the reset threshold with an external resistive

divider. Connect to VCC1 if unused. VRSTIN must not

exceed VCC1.

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.

Supply Input. Powers the device when it is above

VCC2 and monitors its own voltage.
