Product Summary

The STM690TM6F is a 3V supervisor with battery switchover. A precision voltage reference and comparator monitors the VCC input for an out-of-tolerance condition. When an invalid VCC condition occurs, the reset output (RST) is forced low (or high in the case of RST). These devices also offer a watchdog timer as well as a power-fail comparator to provide the system with an early warning of impending power failure.

Parametrics

STM690TM6F absolute maximum ratings: (1)storage temperature: -55 to 150℃; (2)lead solder temperature: 260℃; (3)input or output voltage: -0.3 to VCC+0.3V; (4)supply voltage: -0.3 to 6V; (5)output current: 20mA; (6)power dissipation: 320mW.
