ILC705/706/707/708

mP Supervisory Circuit

General Description

Features

The ILC705/ILC706/ILC707/ILC708 are low cost micro-

processor supervisory circuits that monitor power sup-

plies in microprocessor based systems. Circuit functions

include a watchdog timer, microprocessor reset, power

failure warning and a debounced manual reset input.

! 4.4V or 4.65V Precision Voltage Monitor

! 200ms Reset Pulse Width

! Debounced TTL/CMOS Compatible Manual Reset Input

! Watchdog Timer with 1.6 sec Timeout (ILC705/ILC706)

! Voltage Monitor for Early Power Fail Warning or Low

The ILC705 and ILC706 offer a watchdog timer function

while the ILC707 and ILC708 have an active high reset

output in addition to the active low reset output.

Battery Detect

! 8-Pin SOIC or DIP Package

Applications

Supply voltage monitor levels of 4.65V and 4.4V are

available. The ILC705/ILC707 have a nominal reset

threshold level of 4.65V while the ILC706 and ILC708

have a 4.4V nominal reset threshold level. When the sup-

ply voltage drops below the respective reset threshold

level, RESET is asserted.
