ISL6609CBZ-T is a high-performance gate driver product from Intersil/Renesas. It is an integrated gate driver for a wide range of applications, such as LED backlighting, automotive lighting, motor drivers, and motor control systems. The product includes a 6-channel MOSFET driver, with low RDS(ON) load and up to 18A peak current capability. Additionally, it allows for two types of gate drivers: dual-channel MOSFET drivers with a 70V to 200V maximum drain-source voltage, and single-channel MOSFET driver with a 30V to 60V maximum drain-source voltage. Furthermore, the device is rated for operating junction temperatures of -40C to +125C.

The operating principle of ISL6609CBZ-T is simple. It is a voltage-mode DC-DC converter, utilizing an internal MOSFET bridge, which provides a quiescent point of the desired output voltage. When the output is short-circuited, an internal Vref voltage is applied across the output, causing the MOSFET bridge to become active, shunting current around the output and preventing overcurrent shutdown. The device then monitors the output current and, if it exceeds the pre-defined threshold, automatically turns off the MOSFET bridge, which acts as a switch, to reduce the output current. When the output current drops below the threshold, the MOSFET bridge is re-enabled, and the output voltage is restored to the quiescent setting.

ISL6609CBZ-T makes an ideal choice for gate driving in power management ICs (PMICs), motor control, and LED lighting applications, due to its wide operating temperature range, low RDS(ON) load, and up to 18A peak current capability. It is an especially attractive option due to its capability of two types of gate drivers: dual-channel MOSFET drivers with a 70V to 200V maximum drain-source voltage, and single-channel MOSFET driver with a 30V to 60V maximum drain-source voltage. Furthermore, the device features overvoltage protection and integrated ESD protection to ensure a higher degree of safety in operation.

The ISL6609CBZ-T is an excellent option for high-performance gate driver applications. It offers the capability of two types of gate drivers, a wide operating temperature range, low RDS(ON) load, and up to 18A peak current capability. Additionally, its overvoltage protection and integrated ESD protection enable it to work with a higher degree of safety in operation. With all these features, it is thus an ideal product for PMICs, motor control, and LED lighting applications.
