STM812 Active Low, Push-Pull
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).
技术特性
- Precision monitoring of 3 V, 3.3 V, and 5 V supply voltages
- Two output configurations
- 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
