IR2153PBF

The IR2153PBF is a self-oscillating Half-bridge Gate Driver IC incorporates a high voltage half-bridge gate driver with a front end oscillator similar to the industry standard CMOS 555 timer. The IC provides more functionality and is easier to use. A shutdown feature has been designed into the CT pin, so that both gate driver outputs can be disabled using a low voltage control signal. In addition the gate driver output pulse widths are the same once the rising under-voltage lockout threshold on VCC has been reached, resulting in a more stable profile of frequency vs. time at start-up. Noise immunity has been improved significantly, both by lowering the peak DI/DT of the gate driver and by increasing the under-voltage lockout hysteresis to 1V.

• True micro power start-up
• Tighter initial dead-time control
• Low temperature coefficient dead time
• Shutdown features on CT pin
• Lower power level-shifting circuit
• Constant LO, HO pulse widths at start-up
• Low side output in phase with RT
• Excellent latch immunity on all inputs and outputs
