Product Summary

The IRS21844PBF is high voltage, 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 3.3V logic. The output drivers feature 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.

Parametrics

Absolute maximum ratings:(1)High-side floating absolute voltage, VB: -0.3 to 620V; (2)High-side floating supply offset voltage, VS: VB-20 to VB+0.3V; (3)High-side floating output voltage, VHO: VS-0.3 to VB+0.3V; (4)Low-side and logic fixed supply voltage, VCC: -0.3 to 20V; (5)Low-side output voltage, VLO: -0.3 to VCC+0.3V; (6)Programmable dead-time pin voltage (IRS21844 only), DT: VSS-0.3 to VCC+0.3V; (7)Logic input voltage (IN & SD), VIN: VSS-0.3 to VCC+0.3V; (8)Logic ground (IRS21844 only), VSS: VCC-20 to VCC+0.3V; (9)Allowable offset supply voltage transient, dVS/dt: 50V/ns.

Features

Features:(1)Floating channel designed for bootstrap operation; (2)Fully operational to +600 V; (3)Tolerant to negative transient voltage, dV/dt immune; (4)Gate drive supply range from 10 V to 20 V; (5)Undervoltage lockout for both channels; (6)3.3 V and 5 V input logic compatible; (7)Matched propagation delay for both channels; (8)Logic and power ground +/- 5 V offset; (9)Lower di/dt gate driver for better noise immunity; (10)Output source/sink current capability 1.4 A/1.8 A; (11)RoHS compliant.
