Features

HALF-BRIDGE DRIVER

• Floating channel designed for bootstrap operation

• Fully operational to +600 V

• Tolerant to negative transient voltage, dV/dt

immune

• Gate drive supply range from 10 V to 20 V

• Undervoltage lockout for both channels

• 3.3 V, 5 V, and 15 V input logic compatible

• Cross-conduction prevention logic

• Matched propagation delay for both channels

• High-side output in phase with HIN input

• Low-side output out of phase with LIN input

• Logic and power ground +/- 5 V offset

• Internal 540 ns deadtime, and programmable up

to 5 µs with one external RDT resistor (IRS21084)

Description

The IRS2108/IRS21084 are high volt-

age, high speed power MOSFET and

IGBT drivers with dependent high- and

low-side referenced output channels.

Proprietary HVIC and latch immune

CMOS technologies enable ruggedized

monolithic construction. The logic input

is compatible with standard CMOS or

LSTTL output, down to 3.3 V logic. The

output drivers feature a high pulse cur-
