STM809RWX6F

监控电路 2.63V Reset circuit 140ms

Description  

The STM809RWX6F 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).

Features STM809RWX6F

■ 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
