The ISL61853ACRZ is a integrated hot-swap power load switch that is suitable for hot plug-in of power supplies for industrial, enterprise and communications systems. The device integrates low Rds(on) N-Channel and P-Channel MOSFETs and a robust, adaptive dead-time control circuit. This combination reduces losses in the switch, allowing a safe, efficient and reliable hot-swap solution. The ISL61853ACRZ provides two low-side outputs and one high-side output. The control signal allows the device to be powered up in a safe and reliable manner. The overcurrent protection limits the surge current available, while the thermal foldback limits the maximum output voltage.

The ISL61853ACRZ\'s features and specifications make it a great choice for hot swap applications, such as servers, storage systems and high power embedded devices. It provides a low on-resistance (Rds(on)) and a low profile allowing for efficient operation and higher switch current ratings. The device also reduces power loss due to its thermal foldback, adaptive dead-time and high switching frequency of 2.5 MHz. The device is a fully integrated hot swap solution, which includes both the high-side and low-side switches, an overcurrent protection circuit and thermal protection. Additionally, the ISL61853ACRZ is provided with an extensive set of configurable parameters that offer a wide range of flexibility and customization.

The ISL61853ACRZ has a simple working principle. The device is designed with two low-side output channels and one high side output. The behaviour of the device is determined by the main control signal, which can be provided either by a controller, a microcontroller, or a PWM signal. The control signal is then applied to the main MOSFETs, triggering them to either turn on or off. When the MOSFETs are on, current is allowed to flow through the device. When the MOSFETs are off, current is blocked from flowing. The overcurrent protection limits the surge current available, while the thermal foldback limits the maximum output voltage.
