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.

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.

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.
