HIP2106

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.
