The ILC803, ILC809 and ILC810 are low cost microproces-

sor supervisory circuits that assert a reset if the power sup-

ply drops below a designated threshold. Several different

reset thresholds are available to accommodate systems

operating at 3V, 3.3V or 5V.

The ILC803 has an open drain output stage with active

low RESET output

The ILC809 has an active low RESET output, while

the ILC810 offers an active high RESET output. The

reset output is guaranteed to remain asserted for a

ignated reset threshold. The ILC803, ILC809 and

ILC810 are available in either a 3-Pin SOT-23 pack-

age or a 3-Pin SC-70 packages.
