The is a microprocessor supervisory circuit from Texas Instruments, designed to monitor the power supplies in microprocessor and digital systems, providing a reset signal to the microprocessor during power-up, power-down, and brown-out conditions.

• Operating Voltage Range: -40°C to +85°C
• Active Low, Open-Drain RESET Output: Ensures the microprocessor is held in the reset condition until the power supply is stable.
• Manual Reset Input (MR): Provides an additional layer of control and is useful for debugging and testing.
• Under-Voltage Detection: Precision monitoring of 4.63V power supply conditions.
• Package: 3-pin SOT-23
