Processor Supervisor 4.63V 3V/3.3V/5V 3-Pin SOT-23 T/R

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).

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