The ISL61853HIRZ is a Hot Swap® controller that is designed to regulate the output voltage and current supplied to a load powered from an adjunct supply. The device is designed to be used in an isolated configuration and is capable of providing up to 58V of output voltage. It also features an auto-recover function that monitors the output voltage and will reset the device if the output voltage falls below a set point.

The ISL61853HIRZ is well suited for use in applications such as AC/DC power conversion, LED lighting, server power supplies, telecom power supplies, and solar inverters. This Hot Swap controller is designed to provide protection for a device from overload, short circuit, and overvoltage conditions. It also provides a number of features that can be used to improve system reliability, such as a power-on reset circuit and a configurable over-temperature protection circuit.

The working principle of the ISL61853HIRZ is based on a discrete MOSFET gate drive and error amplifier. The device is capable of controlling an external N-channel MOSFET by using an adjustable reference voltage to set the output voltage and a feedback loop to maintain the voltage at a desired level. The device also provides an enable pin that can be used to enable or disable the control of the MOSFET.

The ISL61853HIRZ is also equipped with a number of protection features designed to prevent damage to the device and the system. These include over-voltage protection, over-current protection, short-circuit protection, and reverse-polarity protection. The device also has a thermal shutdown feature that will shut the device off if the temperature of the die exceeds the rated temperature.

The ISL61853HIRZ is a highly reliable Hot Swap controller capable of providing protection and regulation for a wide variety of applications. It features an adjustable reference voltage and feedback loop that can be used to regulate an external MOSFET and provide a reliable source of power. In addition, the device is equipped with a number of protection features to ensure the safety of the system.
