The ISL6612BIB is a 3-bit high-voltage gate driver designed to drive the gates of N-channel MOSFETs and IGBTs. It is part of the PolarHigh™ family of integrated power management products and is available in a variety of packages, including the industry-standard 28-lead SSOP and the 8-pin SOIC. It utilizes a unique, patented architecture to ensure the device is able to drive two outputs (main and auxiliary) up to 6.0V with programmable slew rates and built-in protection features. The ISL6612BIB is optimized for use with high voltage switch mode power supplies (SMPS) and is suitable for a variety of applications such as electric power supply, automotive and industrial.

The ISL6612BIB is a three-bit gate driver with both main and auxiliary output capabilities. It has a selectable slew rate for both the main and auxiliary outputs with either 0.3V/us or 2.5V/us options. The main output can drive up to 6.0V gate thresholds and the auxiliary output can drive up to 15V gate thresholds. The various protection features built into the device protect against short circuit conditions, over-current and latch-up. The device also has programmable fault flag outputs and faults are indicated by open-drain flags.

The ISL6612BIB device is powered via an 8 pin SOIC package or 28 lead SSOP package, depending on the application needs. The device is designed to interface directly with a wide variety of logic families, including both CMOS and TTL logic families. The Input logic levels for the device can be either 3.3V or 5V, and the output stages are capable of driving both N-channel MOSFETs and IGBTs. The device requires a 12V supply voltage for operation.

The ISL6612BIB gate driver works by providing pulses to control the flow of the gate-sourced current. The pulses are timed in such a way that the output voltage of the device is controlled in a defined manner, which is referred to as slew-rate controlled voltage. The device also has protection features such as short circuit monitoring, over current sensing, and fault flag outputs to protect against latch-up and other fault conditions. The ISL6612BIB also has the added benefit of being compatible with a wide variety of logic families, making it a very versatile and applicable gate driver for a variety of applications.
