The ISL61853BIRZ-T is a high-accuracy, low-power, hot swap controller in PMIC (power management IC) solutions. This integrated device is designed to provide very precise control of voltage over widely varying conditions. The ISL61853BIRZ-T is a monolithic programmable power management circuit suitable for hot swap, eFuse, and over-current protection applications.

The ISL61853BIRZ-T is specifically designed to provide very precise control of voltage over widely varying conditions, including temperature and current. This allows for more efficient and reliable operation of hot swap applications. It supports a wide variety of input voltage ranges (3-15V) and allows for very precise voltage tracking over the whole range. The device also allows for a programmable fold back current limit to provide additional protection when the input voltage is over-stressed.

The ISL61853BIRZ-T offers two analogue inputs, one for voltage-tracking with 0.1mV resolution and one for current-tracking with 15uA resolution. These inputs can be used to sense current and voltage monitoring of multiple devices, allowing the device to continuously monitor for overvoltage and overcurrent. The device also offers a unique hardware-controlled turn-on sequence, which allows for fast and precise adjustment of power up time.

The ISL61853BIRZ-T also features a highly configurable slew-rate that allows for easy adjustment of slew-rate from fast (slew-rate acceleration) to slow (slew-rate deceleration). This device supports a flexible design for power up and power-down control, which makes it ideal for use in hot swap applications.

The ISL61853BIRZ-T is configured to enable precise control of over-current and over-voltage conditions. It supports both enable and blanking modes, ensuring maximum output power availability in the event of an over-current or over-voltage condition. The precise control of current and voltage also allows for optimal energy management, helping to reduce power consumption.

The ISL61853BIRZ-T enables high accuracy control of output voltage and current, with a maximum output voltage accuracy of ±0.25mV. This ensures precise and reliable control even in high-load conditions, protecting the load from damaging power fluctuations. The device also features programmable overvoltage and overcurrent alarms, providing further protection and preventing potential damage.

The ISL61853BIRZ-T is suited for use in many hot swap applications, providing precise control of output voltage and current under varying conditions. The device’s wide input voltage range (3-15V) allows it to operate in many system configurations, including mobile and server applications. The precision voltage and current control, combined with its overvoltage and over-current protection features, make it an ideal choice for hot swap applications.
