The ISL89164FRTAZ-T is a highly efficient, low propagation delay, ultra low-power, 4-A dual low-side gate driver integrated circuit. It is designed specifically to drive low-side gate drivers such as MOSFETs, bipolar transistors and Darlington drivers in a variety of automotive, industrial, medical and computing applications. The device consists of two independent gate drivers in a 6-lead TSSOP package. The built-in charge-pump voltage translation structure allows it to drive both high and low side devices in the same package space.The sophistication of the ISL89164FRTAZ-T lies in its ultra low-power operation and low propagation delay. This makes it an ideal choice for power saving and real time response needs in many applications. Furthermore, Intelligent thermal foldback keeps the device from overheating, even during high load conditions.

The device includes a Wide Vin undervoltage lockout, a low-voltage soft-start, a Charge-pump voltage translation and a high-speed open-collector output (with pull up resistor) all of which result in improved system performance, power savings and increased safety. The IC is designed to operate over a wide supply range, making it suitable for applications requiring a wide range of input voltages.

The ISL89164FRTAZ-T working principle is straightforward and efficient. The supply voltage is used to generate a charge-pump voltage, which is then used to drive the high side and low side gate drivers that control the switching of the MOSFETs or other power devices. The low-side driver also functions as an open-drain output for controlling external logic gates or driver circuitry.

The application field of the ISL89164FRTAZ-T includes applications such as automotives, industrial controls, medical, computing and more. In automotives, the IC is used for controlling powertrain actuators, such as fuel injectors, air intake valves and exhaust gas recirculation (EGR) solenoid valves. In industrial controls, it can be employed to switch large loads, such as motors and pumps. Furthermore, in medical applications, the device powers devices such as dental chairs, patient monitors and implanted medical devices. Finally, the IC is also used in computing applications, such as data center DC-DC power supplies, server power supplies and mission critical systems.

In conclusion, the ISL89164FRTAZ-T is an efficient, ultra low-power integrated circuit design specifically suited for gate driver applications. It is well-suited for a wide range of automotive, industrial, medical and computing applications due to its exceptional power efficiency, low propagation delay and wide input voltage range capabilities.
