Description
The A6387 is a high voltage device,
manufactured with the BCD™ “offline”
technology. It is a single chip half-bridge gate
driver for N-channel Power MOSFETs or IGBTs.
The high-side (floating) section is designed to
stand a voltage rail of up to 550 V. The logic
inputs are CMOS/TTL compatible for easy
interfacing of the microcontroller or DSP.

Applications
 Drive inverters for HEV and EV
 HID ballasts, power supply units
 Motion driver for home appliances, factory
automation, industrial drives
