TC51
1пЃ­A Voltage Detector with Output Delay
Features 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 1пЃ­A 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. Precise Detection Thresholds: В±2.0%
Small Package: 3-Pin SOT-23A
Low Supply Current: Typ. 1пЃ­A
Wide Detection Range: 1.6V to 6.0V
Wide Operating Voltage Range: 0.7V to 10V
Built-in Delay Circuit: 50msec to 200 msec
Open-Drain Output The device includes a comparator, low-current highprecision reference, laser-programmed voltage divider,
hysteresis circuit and output driver with digital delay
timer. Applications Battery Voltage Monitoring Microprocessor Reset System Brown-out Protection Device Selection Table

Technology Inc. for details. In operation, the TC51’s output (VOUT) remains in the
logic HIGH state as long as VIN is greater than the
specified threshold voltage (VDET -). When VIN falls
below VDET -, the output is immediately driven to a logic
LOW. VOUT remains LOW until VIN rises above VDET by an amount VHYST, whereupon it returns to a logic …
