STM811TW16F Datasheet PDF - ST Microelectronics

The STM811TW16F is an active low push-pull Microprocessor Unit Reset Circuit used to monitor power supplies. This performs a single function asserting a reset signal whenever the VCC supply voltage drops below a preset value and keeping it asserted until VCC has risen above the preset threshold for a minimum period of time.

● Two output configurations push-pull RST output

● 6µA Typical low supply current

● Guaranteed RST/RST assertion down to 1VCC
