100V/1A Peak, Low Cost, High Frequency
Half Bridge Driver
The HIP2106 is a high frequency, 100V Half Bridge
N-Channel MOSFET driver IC, available in 8 lead plastic
SOIC. The low-side and high-side gate drivers are
independently controlled and matched to 8ns. This gives the
user maximum flexibility in dead-time selection and driver
protocol. 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 levelshifter 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.
