PMIC - Gate Drivers

The Integrated Full-Bridge MotorgateDriver ISL6612IB-T combines a high-side and a low-side driver in a single die solution. It is designed to operate with an inductive motor driver in an H-bridge configuration, which provides the managed power and direction signals to an inductive motor. It is specifically designed to drive both brushed and brushless DC motors without any additional components. The ISL6612IB-T includes integrate an over-current protection circuit, providing an adjustable current set point, and internal protection on open load, overvoltage and over temperature.

This gate driver has been designed to drive both high-side outputs and low-side outputs of the H-bridge as long as the total peak current does not exceed 3.2A. As such it is designed for applications where the equivalent of a DC motor current of 1.6A or higher is required. The device provides a wide range of protections, including current, over-voltage, under-voltage, short circuit and thermal shutdown.

The ISL6612IB-T effectively combines two independent single-channel drivers in a single package and it is ideal for almost any motor driver application. The range of operating supply voltage is from 10V to 18V, so it can be used in both low voltage and high voltage motor control applications. Other features include galvanically isolated driver inputs, on-chip bootstrap capacitors and an output power stage built to minimize EMI. The product also includes over-current protection, adjustable via an external resistor.

The ISL6612IB-T is compatible with most motor control interface protocols, such as RS232, Pulse-Width Modulation (PWM) and PLCs. In addition, it is designed with an integrated pulse width modulation (PWM) generator to provide high-frequency, high current drive for motors, as well as for other applications. It also includes a bootstrap circuitry that helps maintain a high gate voltage to the MOSFETs and outputs current up to 3.2A peak.

The ISL6612IB-T can also be used to drive LED arrays, LED backlights and other types of electronic loads. It is designed with a low power consumption and low electromagnetic interference (EMI) features. The device also features a wide temperature range of -40 °C to +125 °C and is RoHS compliant.

In conclusion, the ISL6612IB-T is a versatile, high-efficiency gate driver that is designed specifically for motor control applications such as DC motors, brushless motors, and LED backlighting. It combines two full-bridge drivers in a single package, allowing it to accept a wide range of supply voltage from 10V to 18V. The device has a variety of operational, safety and protection features, making it ideal for powering and controlling a wide range of motors and other applications. It is designed to offer superior performance, and its wide operating temperature range makes it suitable for use in a variety of environments.
