ISL61863HCRZ-T Datasheet/PDFThe ISL61863HCRZ-T is a general-purpose Hot Swap Controller that provides safe inrush current limiting, precision input voltage regulation, and precise output voltage control. The device prevents damages caused by reverse currents, input or output overvoltage, and output undershoots, as well as providing a host of features to protect and control advanced systems.
Application fields for this Hot Swap Controller include Telecommunications, Data Systems, Portable Electronics, Industrial Automation, Automotive and Networking applications, among others. It is designed to operate with industrial temperature (I/O pins) from –40°C to 115°C and junction temperature from –40°C to 150°C.
The purpose of a Hot Swap Controller is to safely turn on and off a load in power system applications without triggering a fault due to overcurrent or out-of-range voltages. The ISL61863HCRZ-T has built-in features that protect against these faults.
The device includes a comprehensive set of features formed by drain voltage regulation, adjustable over-current protection, output in-rush limiting, and adjustable slew rate control. It allows the user to co-ordinate the turn-on and turn-off of multiple power supplies with a single control signal. It also provides an internal voltage reference and a buffered output voltage for extreme temperature performance.
The ISL61863HCRz-T\'s operating principle consists of two main procedures: Initialization and the Controlled Start-up. During initialization, the device monitors the input voltage and bridge control inputs, allowing the output transistor to be turned off in case of a short circuit or an over-voltage event. During the controlled start-up phase, the device turns on the output transistor by accurately controlling the output voltage, avoiding sudden current spikes.
The ISL61863HCRZ-T is a versatile Hot Swap Controller capable of providing precise control and protection in high-power applications. It allows the user to design robust systems that are safe to operate in various temperatures, voltage levels, and load conditions. As it is integrated with a vast array of features, this Hot Swap Controller is an affordable and reliable solution for designers looking for output voltage control, overcurrent protection, and inrush current limiting.
