ISL89160FRTBZ

The ISL89160FRTBZ is a gate driver PMIC (power management integrated circuit) that can provide up to 18A per output and is ideal for driving high power MOSFETs/IGBTs. It is designed as a non-inverting and four-output driver that also features integrated primary side controllers and fail-safe protection circuitry. The ISL89160FRTBZ is suitable for applications such as motor control, UPS, solar, consumer, industrial and automotive.

The ISL89160FRTBZ is a power management integrated circuit (PMIC) designed with multiple independent low side, high side and switch timer controllers. It includes an adjustable slew rate soft-drive (Autofold) circuit, which improves flying start performance and reduces EMI noise. The output stages feature over-current, over-temperature and short circuit protection in all load channels. The ISL89160FRTBZ is capable of supplying higher driving currents than most gate drivers, making it suitable for high power applications encountered in certain PCU (Power Control Unit) and other devices.

The ISL89160FRTBZ features integrated primary side controllers that provide synchronous buck, boost, inverting and reset functions for flexibility and to reduce external components. It also offers high linearity analog-to-digital, digital-to-analog, and FET (field effect transistor) gate drive converters for improved performance. The device features a PWM trigger output for driving external switches, and an enable pin for reduced system power dissipation.

The ISL89160FRTBZ also features integrated fail-safe protection circuitry. This ensures that operation is maintained in the event of open or short drain connections to the gate pins. The device is protected against gate voltage ringing and gate-charge pulse exceeding the rated peak gate voltage. It also provides protection against demagnetization by detecting a low speed of the motor when the sensed current is below the programmed IERR.

The ISL89160FRTBZ is ESD-protected up to ±2kV human body model and up to ±2kV charged device model. It also includes thermal shutdown, over-current protection, under-voltage lockout, and over-voltage protection. The device is available in a 48-pin, 4mm x 4mm QFN package and is specified from -40°C to 85°C.

In conclusion, the ISL89160FRTBZ is a versatile, efficient and robust gate driver PMIC for high power applications that require high current outputs. Its many features, integrated primary side controllers, fail-safe protection, ESD protection and QFN package make it suitable for a wide range of applications.
