NCP4330 Datasheet (ON Semiconductor) - Post Regulation Driver

NCP4330, Post Regulation Driver

S) Function “HS_DRV” is the gate driver of the high *side MOSFET.

“BST” is the bootstrap pin.

A 0.1 mF to 1.0 mF ceramic capacitor should be connected between this pin and the node that is common to the coil and the two MOSFET.

The “BST” voltage feeds the high *side driver (“HS_DRV”).
