Product Highlight

  • No of Outputs: Single
  • Threshold Voltage: 3.08 V
  • Supply Voltage-Max: 5.5 V
  • Reset Timeout: 140 ms

The STM809TWX6F is a low power supervisory microprocessor Reset circuit used to monitor power supplies.
This performs 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.


  • Precision monitoring of 3 V, 3.3 V, and 5 V supply voltages
  • Push-pull RST output
  • 140 ms reset pulse width
  • Low supply current - 6 µA (typical)
  • Guaranteed RST / RST assertion down to VCC = 1.0 V
  • Operating temperature –40 °C to 85 °C
  • Lead-free


  • Motor control
  • Multimedia convergence
  • Power supplies and converters
  • Process control and automation
