STM809_10 Datasheet, PDF (1/21 Pages) STMicroelectronics – Reset circuit

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
V_CC = 1.0 V
■ Operating temperature:
–40 °C to 85 °C (industrial grade)
■ Lead-free, small SOT23 and SOT143 package
