Description

This is SELF-OSCILLATING HALF-BRIDGE DRIVER. Previous Datasheet Index Next Data Sheet Data Sheet No. PD-6.034G IR2151 SELF-OSCILLATING HALF-BRIDGE DRIVER Features n Floating channel designed for bootstrap operation Fully operational to +600V Tolerant to negative transient voltage dV, dt immune n Undervoltage lockout n Programmable oscillator frequency Product Summary VOFFSET Duty Cycle IO+, VOUT Deadtime (typ.) 600V max. 50% 100 mA , 210 mA 10 - 20V 1.2 s f = 1 1.4 × (R T + 75Ω) × CT n Matched propagation delay for both channels n Low side output in phase with RT Description The IR2151 is a high voltage, high speed, self-oscillating power MOSFET and IGBT driver with both high and low side referenced output channels. Proprietary HVIC and latch immune CMOS technologies enable ruggedized monolithic construction. The front end features a programmable oscillator which is similar to the 555 timer. The output drivers feature a high pulse current buffer stage and an internal deadtime designed for minimum driver cross-conduction.
