ISL61862DIRZ-T

Power Manager IC (PMIC) - Hot Swap Controllers provide a reliable, efficient, and cost-effective means of controlling inrush currents and ensuring power supplies remain operational in the event of power failure or over current conditions. The ISL61862DIRZ-T is specifically designed to provide hot-swap protection, including pre-charge and inrush current control, discharge of input capacitors, UV/OV protection.and current limiting in hot-swap applications.

The ISL61862DIRZ-T is an integrated hot-swap controller which enables board hot-swapping of high-power 12V systems. It integrates a dual-channel MOSFET driver with a slow start pre-charge protection (WLP) circuit, adjustable over-voltage and under-voltage protection, current limiting and thermal shutdown protection, as well as two loop-back status outputs.

The ISL61862DIRZ-T is also used as a controller for hot-swap boards. It integrates two MOSFET drivers for Hot Swap applications and provides 13V OV/UV supply threshold at 12V input level. It also features a power-on reset (POR) circuit, under-voltage lockout (UVLO), adjustable current limit, thermal shutdown and loopback status outputs. This results in fewer discrete components and more cost-effective solutions.

ISL61862DIRZ-T provides superior hot-swap design compared with other PMIC devices by its self-biased MOSFET driver, eliminating the requirement for expensive discrete external MOSFETs. The pre-charge has a time delay (adjustable) and often used to reduce potential inrush current at the system power-on, which could damage supply lines and other components.

The ISL61862DIRZ-T is also capable of efficient current limiting in hot-swap applications. Its adjustable current limit is set such that if an over-current occurs, current will automatically be limited to safe levels. This prevents equipment damage and protects the line circuit, potentially extending system life. Additionally, the ISL61862DIRZ-T has a built-in thermal shutdown feature to protect the power source in high temperature environments.

The ISL61862DIRZ-T offers a variety of features including configurable pre-charge voltage, adjustable current limit, adjustable over-voltage protection, adjustable under-voltage protection, and loop back status outputs to provide efficient and reliable hot swap protection in a wide range of applications. It is also versatile when it comes to voltage rail regulation as it supports a wide input voltage range and high power efficient operating modes.

In summary, the ISL61862DIRZ-T is a versatile hot-swap controller that can be used in applications such as board hot-swapping, voltage rail regulation, and current limit current protection for high power systems. It integrates an adjustable and configurable pre-charge, adjustable current limit, adjustable OV/UV protection, and thermal and loop-back protection in a single device. The ISL61862DIRZ-T is an ideal choice for high power systems and hot-swap applications as it provides a cost-effective and reliable means of power management.
