Processor Supervisor 4.63V 3V/3.3V/5V 3-Pin SOT-23 T/R

The STM809/810/811/812 MICROPROCESSOR RESET Circuits are low-power supervisory devices used to monitor power supplies. They perform 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 (trec). The STM811/812 also provide a push-button reset input (MR).

Precision monitoring of 3 V, 3.3 V, and 5 V supply voltages

Two output configurations Push-pull RST output (STM809/811) Push-pull RST output (STM810/812)

140 ms reset pulse width (min)

Low supply current - 6 µA (typ)

Guaranteed RST/RST assertion down to VCC = 1.0 V

Operating temperature: 40 °C to 85 °C (industrial grade)

Lead-free, small SOT23 and SOT143 package
