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
2µA 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.
