The HIP2101 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 force the outputs low. An
on-chip diode eliminates the discrete diode required with
other driver ICs. A new level-shifter topology yields the lowpower 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.
