• High-Voltage Drives
• DC-DC Converter

Working Principles of ISL89163FRTBZ

ISL89163FRTBZ contains a high and low side gate driver circuit with a shift capability of up to ±20V. It has a tolerant power supply voltage range of 6V to 40V, which means that the customer does not need to use many components for the power supply design.The gate driver consists of two power switches on the same integrated circuit and has a common gate control interface. A high side or low side MOSFET (Metal Oxide Field Effect Transistor) can be driven without any requirement of external components. The internal feedback loop helps to detect the ON or OFF status of the power switch and the UVLO (Under Voltage Lock Out) Functionality provides auto-shut down to the MOSFETs to protect them from low-voltage failure.The ISL89163FRTBZ also ensures low power consumption to reduce the cost and increase the efficiency. By varying the voltage levels, power supplies in the customer systems will be adjusted to meet their application’s operating requirements, while still maintaining the same temperature.The integrated power switch driver in the ISL89163FRTBZ also helps to dramatically reduce the losses due to resistance in the signal lines. It also reduces the system power consumption and complexity due to the reduced current flow through the signal lines.

Conclusion

ISL89163FRTBZ is a high-performance integrated power switch driver from PMIC - Gate Drivers that helps customers to minimize the complexities and reduce the PCB space and system power supply design for automotive applications. It also ensures that customers get the best performance with its features such as a wide supply voltage range, feedback loop for status detection, adjustable current and voltage levels, thermal protection, and low power consumption.
