AMG-DF102

Full Bridge MOSFET/IGBT Driver up to 600V

1. Functional Description of the AMG-DF102

The AMG-DF102 is a high voltage MOSFET and IGBT driver with two dependent high and low

side output channels for Full-Bridge applications. The IC AMG-DF102 has an additional driver

in high side configuration to drive a buck converter.

CMOS and TTL compatible input levels. Logic inputs are CMOS Schmitt-triggered with pull-

down resistors.

The floating high side outputs are designed for bootstrap operation so to drive an N-channel

power MOSFET or IGBT in high side configuration.

During start up the input ENQ need to be tied to VCC to pull the driver outputs low. With ENQ

being pulled low, the device is enabled. This protects against unwanted behaviour of the

power stage during the start up process, when the supply voltage is rising.
