STM810:Active High, 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).

Key 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)
