Microchip Voltage Supervisor 3V max. 4-Pin SOT-143, TC1270ATVRCTR [TC1270ATVRCTR]; 598-301

The Microchip Voltage supervisor circuit designed to monitor supply voltage levels in digital systems and ensure reliable system resets. It asserts a reset signal when the supply voltage drops below a preset threshold, helping prevent erratic behaviour during power-up or brownout conditions. The device includes a manual reset input for push-button control and features a push-pull, active-low reset output. With precision voltage trip points and glitch-free operation during power transitions, it's ideal for battery-powered and embedded applications.

No glitches on outputs during power-up
