HIP2101IBZT

HIP2101IBZT is a high frequency, 100V half-bridge N-channel power MOSFET driver IC. It is equivalent to the HIP2100 with the added advantage of full TTL/CMOS-compatible logic input pins. The low-side and high-side gate drivers are independently controlled and matched to 13ns. This gives users total control over dead time for specific power circuit topologies. Undervoltage protection on both the low-side and high-side supplies forces the outputs low. An on-chip diode eliminates the discrete diode required with other driver ICs. A new level-shifter topology yields the low-power benefits of pulsed operation with the safety of DC operation. Unlike some competitors, the high-side output returns to its correct state after a momentary undervoltage of the high-side supply. Applications include telecom half bridge power supplies, avionics DC-DC converters, two-switch forward converter, active clamp forward converters.
