Overview
The LMS33460MGX/NOPB is a supervisor IC designed by Texas Instruments, a leading manufacturer in the semiconductor industry. This device is part of the Power Management ICs (PMIC) family and is specifically engineered for precise voltage monitoring and power-on reset functionality. It is an ultra-low power, 3-V undervoltage detector that ensures system reliability by monitoring the supply voltage and asserting a reset signal when the voltage drops below a predetermined threshold. The LMS33460MGX/NOPB is particularly suited for battery-powered systems where low quiescent current and small package size are critical.
