The ISL95874HRUZ-T integrated circuit (IC) is an efficient, low-voltage polarity protection power management IC (PMIC) that belongs to the special purpose voltage regulator class. It is designed to provide protection from over-voltage and electrostatic discharge (ESD) that may be encountered in automotive, industrial and consumer system applications.

The IC is designed with a wide input voltage operating range between 5V and 18V to withstand varying voltage surges. It features low on resistance and fast switching capability to ensure optimal power supply stability, reduce current consumption and ensure a sustained level of performance. The IC is integrated with two N-Channel MOSFETs in a half-bridge configuration, providing excellent reverse-current protection even in the case of an automotive battery disconnect event.

The half-bridge IC is integrated with several circuits and components that serve to protect against ESD and voltage transients. An external switching capacitor is used to set the propagation delay required to protect against transient spikes. The other component is a differential amplifier that monitors the input pins to detect the presence of an over-voltage condition. The voltage regulator features a built-in non-inverting amplifier with a hysteresis voltage control circuitry, which controls the on/off conditions of the MOSFETs. This hysteresis voltage regulator helps to desensitize the circuit to reduce sensitivity to ESD and other transient effects.

At a general system level, the ISL95874HRUZ-T is used to couple an output voltage to a power supply, allowing for improved efficiency and power management. When an overvoltage is detected, the two N-channel MOSFETs will open and decouple the output from the main power supply. This ensures that any undesirable voltage spikes do not affect the functioning of the system. Furthermore, the built-in hysteresis and differential amplifier can detect over-voltage conditions and isolate the input signal from further damage.

In addition, the ISL95874HRUZ-T is equipped with a low quiescent current and low hold up time. This helps to ensure that the output is stable, regardless of input changes in the system. Moreover, the device features thermal shutdown and an integrated soft-start circuit that prevents inrush current to the system, ensuring a safe and reliable power supply.

The ISL95874HRUZ-T is suitable for use in a variety of systems including automotive, industrial, and consumer systems. Additionally, it is compliant with the ISO/IEC7816-3 international standard and is designed in compliance with the IPC/JEDEC J-STD-20 footprint for efficient board-level integration.
