TC54VN4502ECB713

The TC54VN4502ECB713 is a CMOS voltage detector designed by Microchip Technology Inc., specifically suited for battery-powered applications due to its extremely low 1 µA operating current and small surface-mount packaging. This device features detection thresholds with a ±2.0% tolerance, available in standard trip points from 1.4V to 6.0V. The TC54 series, including the TC54VN4502ECB713, operates over a wide voltage range from 0.7V to 10V.

Key electrical characteristics include a typical quiescent current of 1 µA and a wide detection range from 1.1V to 6.0V. The device is available in compact packages such as 3-Pin SOT-23A, SOT-89, and TO-92, with surface mount options. The output stage is open-drain, which remains in a logic-high state as long as the input voltage (VIN) is greater than the specified threshold voltage (V_DET). When VIN falls below V_DET, the output is driven to a logic-low state and remains low until VIN rises above V_DET by an amount V_HYST.

Applications for the TC54VN4502ECB713 include battery voltage monitoring, microprocessor reset, system brown-out protection, and switching circuits in battery backup systems. Its low current drain and precise threshold voltages make it an efficient choice for power-sensitive designs.
