NCP5106A, NCP5106B
High Voltage, High and Low
Side Driver
The NCP5106 is a high voltage gate driver IC providing two
outputs for direct drive of 2 N−channel power MOSFETs or IGBTs
arranged in a half−bridge configuration version B or any other
high−side + low−side configuration version A.
It uses the bootstrap technique to ensure a proper drive of the
high−side power switch. The driver works with 2 independent inputs.
