General Description

The TC53 is a low power voltage detector. Typical

supply current consumption is only 1

µA at an input

voltage of 2V. The voltage detection threshold setting is

factory-programmed and guaranteed to ±2% accuracy.

Threshold settings are available over a range of 1.6V

to 6.0V. The TC53 has both complementary (CMOS)

and open drain (NMOS) output configuration options.

TC53 is the ideal voltage detector for precision

applications in which small size, low installed cost, high

accuracy and low supply current consumption are

critical.
