Dual Driver IC, Half Bridge, 10V-20V Supply, 2.3A Out, 270ns Delay, SOIC-14Product OverviewThe IR21844SPBF is a high voltage high speed power MOSFET and IGBT Half-bridgeDriver with dependent high and low-side referenced output channels. ProprietaryHVIC and latch immune CMOS technologies enable ruggedized monolithicconstruction. 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 stagedesigned for minimum driver cross-conduction. The floating channel can be usedto drive an N-channel power MOSFET or IGBT in the high-side configuration whichoperates up to 600V.Floating channel designed for bootstrap operationTolerant to negative transient voltage (dV/dt immune)Under-voltage lockout for both channels3.3 and 5V Input logic compatibleMatched propagation delay for both channelsLogic and power ground ±5V offsetLower di/dt gate driver for better noise immunityOutput source/sink current capability 1.4/1.8AApplicationsPower ManagementProduct InformationNo. of Channels: 2ChannelsDriver Configuration: Half BridgePower Switch Type: IGBT, MOSFETSupply Voltage Min: 10VSupply Voltage Max: 20VDriver Case Style: SOICInput Type: Non-InvertingIC Case / Package: SOICNo. of Pins: 14PinsIC Mounting: Surface MountSource Current: 1.9AInput Delay: 680nsOutput Delay: 270nsSink Current: 2.3AOperating Temperature Min: -40°COperating Temperature Max: 125°CMSL: MSL 3 - 168 hours
