Description

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 3V, 3.3V or 5V.

The ILC811 has an active low RESET output, while the ILC812 offers an active highRESET output. The reset output is guaranteed to remain asserted for a minimum of 140ms after V_CC has risen above the designated reset threshold. The ILC811/ILC812 is available in a 4-pin SOT-143
