General Description
The device is a half-bridge gate-driver for driving power ponents such as N-type MOSFETs or IGBTs. The high-side gate-driver is suitable for design with a bus voltage up to 600V. The remended VCC operating voltage is 10V to 20V for power ponents. The logic inputs are patible with standard CMOS or TTL down to 3.3V for easy interfacing control units such as microcontrollers or DSP. The device also integrates two internal protection functions: VCC Power Supply Input Under Voltage Lock-Out and Bootstrap Output Under Voltage Lock-Out. The protection functions can prevent the power ponents from operating in low efficiency or dangerous conditions.
