Product Summary

The IR2109 is a high voltage, high speed power MOSFET and IGBT 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 of the IR2109 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 600 volts.

Parametrics

IR2109 absolute maximum ratings: (1)VB High side floating absolute voltage -0.3 to 625; (2)VS High side floating supply offset voltage VB - 25 to VB + 0.3; (3)VHO High side floating output voltage VS - 0.3 to VB + 0.3; (4)VCC Low side and logic fixed supply voltage -0.3 to 25; (5)VLO Low side output voltage -0.3 to VCC + 0.3; (6)DT Programmable dead-time pin voltage (IR21094 only): VSS - 0.3 VCC to + 0.3; (7)VIN Logic input voltage (IN & SD): VSS - 0.3 VCC to + 0.3; (8)VSS Logic ground VCC: - 25 VCC to + 0.3; (9)dVS/dt Allowable offset supply voltage transient: 50 V/ns.

Features

IR2109 features: (1)Floating channel designed for bootstrap operation. Fully operational to +600V. Tolerant to negative transient voltage dV/dt immune; (2)Gate drive supply range from 10 to 20V; (3)Undervoltage lockout for both channels; (4)3.3V, 5V and 15V input logic compatible; (5)Cross-conduction prevention logic; (6)Matched propagation delay for both channels; (7)High side output in phase with IN input; (8)Logic and power ground +/- 5V offset.; (9)Internal 540ns dead-time, and programmable up to 5us with one external RDT resistor (IR21094); (10)Lower di/dt gate driver for better noise immunity; (11)Shut down input turns off both channels.
