Microchip Voltage Supervisor 3-Pin SOT-23B, MCP102T-450E/TT

The Microchip MCP102 is a Voltage Supervisor that keeps a Microcontroller or other device in Reset during a Brownout event via an active-low Reset Pin.

Ultra-Low Supply Current: 1.75 μA (steady-state maximum)
Resets Microcontroller in a Power-Loss Event
RST Pin: Active-low, push-pull
Reset Delay Timer (120 ms delay, typical)

The Microchip MCP102 MicroPower voltage supervisor is designed to keep a microcontroller in reset until the system voltage has reached and stabilized at the proper level for reliable system operation. It operates on 1V to 5.5V voltage range.

Ultra low supply current of 1.75uA
Precision monitoring of 4.38V
Resets microcontroller in a power-loss event
Active-low, push-pull RESET pin
Reset Delay Timer (120ms delay, typ.)
Temperature range between -40°C and 125°C
3-lead SOT-23 package
