Features & Applications

The STM811MW16F is a 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).

Features:

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
