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 TC51 includes a comparator, low-current highprecision reference, laser-programmed voltage divider, hysteresis circuit and output driver with digital delay timer.

In operation, the TC51's output (V_OUT) remains in the logic HIGH state as long as V_IN is greater than the specified threshold voltage (VDET-). When V_IN falls below V_DET -, the output is immediately driven to a logic LOW.V_OUT remains LOW until V_IN rises above V_DET - by an amount V_HYST, whereupon it returns to a logic HIGH after expiration of the built-in delay time.
