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
