IR21844SPBF

IR21844SPBF is a high voltage, high-speed power MOSFET and IGBT half-bridge driver 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 3.3V logic. The output driver features a high pulse current buffer stage designed for minimum driver cross-conduction. The floating channel can be used to drive an N-channel power MOSFET or IGBT in the high-side configuration which operates up to 600V.

• Floating channel designed for bootstrap operation, fully operational to +600V
• Tolerant to negative transient voltage dV/dt immune, IN/active low SD input logic
• Gate drive supply range from 10 to 20V, undervoltage lockout for both channels
• 3.3V and 5V input logic compatible, matched propagation delay for both channels
• Logic and power ground +/- 5V offset, lower di/dt gate driver for better noise immunity
• Output source/sink current capability 1.4A/1.8A, cross conduction prevention logic
• Dead time range program 0.4 to 5us, VSS/COM ground pins
• Turn-on propagation delay is 680nsec typ (VS=0V, TA=25°C)
• Turn-off propagation delay is 270nsec typ (VS=0V or 600V, TA=25°C)
• 14 lead SOIC package, ambient temperature range from -40 to 125°C
