Power management integrated circuits (PMICs) are components that are responsible for delivering the exact voltages and currents at various locations within an electronic device. PMICs provide the power basis for improved run times, voltage regulation, and temperature monitoring – all critical needs in many industrial applications. Hot swap controllers are a subset of PMICs designed to manage the process of safely connecting and disconnecting two parts of a circuit while the power is still on. The ISL61853JIRZ hot swap controller is an exampledesigned to provide simple features for inrush current limit, load current limit, load disconnect, and load restore.

The ISL61853JIRZ is an automotive grade N-channel hot-swap controller that uses an integrated charge pump to provide a power supply rail of 4.2V in order to drive high-side and low-side FETs. This dual-channel solution provides power switch capabilities with two independent P-Channel FETs on the high-side, two independent N-Channel FETs on the low-side and two power switches. The two MOSFETs are connected in a same-source circuit configuration, one MOSFET used to provide the required inrush current limit, and the other used to provide the required load current limit. The two MOSFETs also act as a power switch, separating the supply rail from ground, thereby allowing the load to be safely powered down.

The ISL61853JIRZ requires a 4.5V – 5.5V supply rail to function, and features protection against undervoltage and overvoltage conditions. It supports load current monitoring, load power down, and device power up. The device also features adjustable gate drive, shutdown threshold, and automatic reset and delay. The device provides adjustable undervoltage and overvoltage protection, as well as over temperature protection with active thermal management. All of these features can be independently and dynamically adjusted without any need for external circuitry or software modification. In addition to these features, the device allows configurable start-up and shut-down thresholds, and adjustable dead-time values.

The ISL61853JIRZ hot swap controller is designed to fit a wide range of industrial applications, and is particularly suited for automotive design. The device can be used in applications that require hot swapping of loads, such as automotive infotainment systems, battery charging/discharging systems, power supplies, and motor control systems. The device provides a reliable and easy to use solution for safely connecting and disconnecting two sections of a circuit under power.

In summary, the ISL61853JIRZ hot swap controller is an automotive grade, dual-channel solution for power switch applications that provides adjustable gate drive, undervoltage and overvoltage protection, over temperature protection, and load power down. This device is ideal for applications that require hot swapping of loads, such as automotive infotainment systems, battery charging/discharging systems, power supplies and motor control systems. The device offers a reliable and easy to use solution for safely connecting and disconnecting two sections of a circuit under power.
