Product overview

Description

The STM1001 microprocessor reset circuit is a low-power supervisory device used to monitor power supplies. It 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 (trec).
  • All features

    • Lead-free, small SOT23 package
    • Operating temperature:–40 °C to 85 °C (industrial grade)
    • Precision monitoring of 3 V, 3.3 V, and 5 V supply voltages
    • 30 ms or 140 ms reset pulse width (min)
    • Open drain RST output
    • Guaranteed RST assertion down to VCC= 1.0 V
    • Low supply current - 6 μA (typ)
