1 — — — RST1 Active-Low, CMOS Reset Output Referenced to V
CC
1
— 1 1 1 RST
Active-Low Reset Output. Open drain for the MAX6352/
MAX6355/MAX6358, push-pull with respect to V
CC
1 for
the MAX6353/MAX6356/MAX6359, and push-pull with
respect to V
CC
2 for the MAX6354/MAX6357/MAX6360.
2 2 2 2 GND Ground
3 3 3 3 MR
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 V
CC
1 if unused.
V
MR
must not exceed V
CC
1.
4 4 4 4 V
CC
2
Supply Input. Powers the device when it is above
V
CC
1 and monitors its own voltage.
5 — — — RST2 Active-Low, CMOS Reset Output Referenced to V
CC
2
— — 5 — RSTIN
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 V
CC
1
if unused. V
RSTIN
must not exceed V
CC
1.
— — — 5 WDI
Watchdog Input. If WDI remains either high or low longer than
the timeout period, then reset is triggered. The timer clears
when reset is asserted or whenever WDI sees a rising or
falling edge. Leave unconnected to disable if unused.
6 5 6 6 V
CC
1
Supply Input. Powers the device when it is above V
CC
2 and
monitors its own voltage.
