IRS21531DSTRPBF

IRS21531DSTRPBF is a self oscillating half-bridge gate driver IC using a more advanced silicon platform, and incorporates a high voltage half-bridge gate driver with a front end oscillator similar to the industry standard CMOS 555 timer. HVIC and latch immune CMOS technologies enable rugged monolithic construction. The output driver features a high pulse current buffer stage designed for minimum driver cross-conduction. Noise immunity is achieved with low di/dt peak of the gate drivers.

• Integrated 600V half-bridge gate driver
• CT, RT programmable oscillator
• 15.4V Zener clamp on VCC, +/- 50V/ns dV/dt immunity
• Micropower startup,„ non-latched shutdown on CT pin (1/6th VCC)
• Internal bootstrap FET, excellent latch immunity on all inputs and outputs
• ESD protection on all pins, internal deadtime
• Quiescent VBS supply current is 60µA typical
• Oscillator frequency is 93KHz typical at RT=7.15Kohm
• 8-lead SOIC package
• Junction temperature range from -40 to 125°C
