NAME

WDI

RSTIN

FUNCTION

Watchdog Input. If WDI

remains high or low for

longer than the watchdog

timeout period, the internal

watchdog timer runs out

and the reset output

asserts for the reset

timeout period. The

internal watchdog timer

clears whenever a reset is

asserted or WDI sees a

rising or falling edge. The

watchdog has a long

startup period (35s min)

after each reset event and

a short watchdog timeout

period (1.12s min) after

the first valid WDI

transition. Leave WDI

unconnected to disable

the watchdog timer. The

WDI unconnected-state

detector uses a small

200nA current source.

Therefore, do not connect

WDI to anything that will

source more than 50nA.

Undervoltage Reset

Comparator Input. High-

impedance input for

adjustable reset monitor.

The reset output is

asserted when RSTIN falls

below the 0.626V internal

reference voltage. Set the

monitored voltage reset

threshold with an external

resistor-divider network.

Connect RSTIN to VCC1

or VCC2 if not used.
