ILC811/ILC812

Microprocessor Reset Circuits

General Description

Features

The ILC811/ILC812 is a low cost microprocessor supervisory

circuit that asserts a reset if the power supply drops below a

designated threshold or the manual reset pin is forced low.

Several different reset thresholds are available to

accommodate systems operating at 3 V, 3.3 V or 5 V.

Precision Voltage Monitor for 3 V, 3.3 V or 5 V Power

Supplies

6 µA Supply Current

140 ms Minimum Reset Pulse Width

RESET Remains Valid with V_CCas Low as 1.4V

Active Low Manual Reset Input

No External Components

The ILC811 has an active low RESET output, while the

ILC812 offers an active high RESET output. The reset output

is guaranteed to remain asserted for a minimum of 140 ms

after V_CChas risen above the designated reset threshold. The

ILC811/ILC812 is available in a 4-pin SOT-143 package.
