Low Power Voltage Detector IC
CN61C
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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the
device. These are stress ratings only, and functional operation of the device at these or any other
conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure
to absolute maximum rating conditions for extended periods may affect device reliability.
