Package Type

General Description

The TC52 consists of two independent low power

voltage detectors in a space-saving 5-pin SOT-23A

package. Typical supply current consumption is only

2

µA at an input voltage of 2V. The voltage detection

threshold

settings

are

factory-programmed

and

guaranteed to ±2% accuracy. Threshold settings over a

range of 1.5V to 5.0V are available. The TC52 is

available with open drain (NMOS) configurations.

Small size, high precision, low supply current, and low

installed cost makes the TC52 the ideal voltage

detector for a wide variety of voltage monitoring

applications.
