The TC54VC4102EZB is a monolithic device that is used as a supervisior in Power Management Integrated Circuit (PMIC) applications. It provides protection against overvoltage, undervoltage, and overcurrent conditions, as well as providing reset timing for microprocessors and redundant power supplies. This device allows designers to more easily set up an overvoltage watchdog circuit with adjustable trip points.

The TC54VC4102EZB is designed to be used with high-side power MOSFETs or P-channel MOSFETs. It is an integrated single-channel overvoltage protection (OVP) circuit with adjustable trip points and an overcurrent protection (OCP) circuit. The OVP circuit can detect an input voltage of up to 24V and has a programmable trip point which can be adjusted between 4.5V and 10V. The OCP circuit can detect output current of up to 20A and trip points can be adjusted between 0.1A and 8A.

The TC54VC4102EZB has a low quiescent current of typically 2.3mA, which allows it to operate over a wide range of input voltages while minimizing power consumption. The integrated reset timer provides an additional level of protection by providing a watch dog period after which the device will reset itself if the monitored supply is not within its limits.

The TC54VC4102EZB includes two logic level open-drain outputs that can be used to indicate a present fault condition, or for resetting any attached microcontrollers. The open-drain outputs are protected against overvoltage and can withstand up to 24V.

The TC54VC4102EZB features a wide operating temperature range of -40°C to +125°C, which makes it suitable for use in a wide range of applications. It is also AEC-Q100 qualified and has UL94V-0 flammability rating for automotive applications.

The TC54VC4102EZB provides an ideal solution for overvoltage and overcurrent protection in PMIC applications. It is simple to use and can be configured with a wide range of adjustable parameters, allowing designers to tailor it to meet the exact requirements of their application.
