Product overview

Description

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).
  • All features

    • Lead-free, small SOT23 and SOT143 package
    • Operating temperature: –40 °C to 85 °C (industrial grade)
    • Precision monitoring of 3 V, 3.3 V, and 5 V supply voltages
    • 140 ms reset pulse width (min)
    • Two output configurationsPush-pull RST output (STM809/811)Push-pull RST output (STM810/812)
    • Guaranteed RST/RST assertion down to VCC = 1.0 V
    • Low supply current - 6 µA (typ)
