This integrated circuit (IC) is designed for use in low voltage DC/DC converter applications and offers low capacitance, fast switching signals, as well as a low turn-on/off threshold. The ISL89163FBEBZ-T features a low side N-channel, and it operates from 3.3V to 14V.

The ISL89163FBEBZ-T is a single channel low side driver with a logic high enable, logic low disable, and enable/disable logic pins. The device is capable of providing source peak current of 8A and a sink peak current of 11A. The ISL89163FBEBZ-T also features slew rate control, truncation mode, output undervoltage lockout, slew rate control and fault protection. The part has an adjustable gate turn-on/off delay, fast turn-on/slow turn-off operation and a high dV/dt immunity.

The ISL89163FBEBZ-T has an input logic compatible to 1.8V and 3.3V interface processors, microcontrollers (MCUs), and compliant with 3.3V and 5V logic. This part has a low quiescent current of less than 100µA and is designed for operation in ambient temperatures between -40° and 125°C.

The ISL89163FBEBZ-T application field involves the use of power electronics. It is used in kiosks, point-of-sale, server applications, cars, and other electrical equipment needing low side driver control. It is also suitable for applications such as PC power supply, ac/dc, dc/dc conversion, motor control, wireless power charging, and motor drive.

The working principle of the ISL89163FBEBZ-T is based on the concept of self-oscillation. It works by selectively switching the gate of the MOSFET on and off in order to achieve a desired effect. When the input logic is high, the driver is enabled, thus the gate of the MOSFET will be driven accordingly. When the input logic is low, the driver is disabled, thus the gate of the MOSFET will be driven to the floating state.

The ISL89163FBEBZ-T is a low side gate driver for PMIC applications that can be used to drive MOSFET switches and provide better signal integrity for low voltage DC/DC converter applications. Its application field consists of power electronics such as kiosks, point-of-sale, server applications, cars, and other electrical equipment. It works by self-oscillation and enables/disables the gate of the MOSFET according to the input logic.
