General Description

The CN61C series is a highly precise and low power consumption voltage detector IC. It provides excellent circuit reliability and low cost by eliminating external components.

The CN61C series performs a single function, it outputs a low level at RES pin whenever the VCC supply voltage declines below a preset threshold, keeping it asserted until VCC has risen above the detection threshold plus a hysteresis.

The CN61C series provides CMOS output or open drain output. The reset comparator is designed to ignore fast transients on VCC, and the outputs are guaranteed to be in the correct logic state for VCC down to 1.15V over the temperature range.

The device is available in 3 pin SOT23 package.
