TC51 Datasheet PDF - Microchip Technology

General Description
The TC51 is a very low power, open drain output, CMOS voltage detector with built-in delay. It is particularly well-suited for battery powered applications because of its extremely low 1µA operating current and small surface-mount packaging. Each part is lasertrimmed to the desired threshold voltage, which can be specified from 1.6V to 6.0V. The standard built-in output delay is 50msec-200msec.
The device includes a comparator, low-current high-precision reference, laser-programmed voltage divider, hysteresis circuit and output driver with digital delay timer.
