The MCP121T-450E/TT is a MicroPower Voltage Supervisor with active-low open-drain output. It is designed to keep a microcontroller in reset until the system voltage has reached and stabilized at the proper level for reliable system operation.
● Resets microcontroller in a power-loss event
● 1.75µA Ultra-low supply current (steady-state maximum)
