The Future of Analog IC Technology
DESCRIPTION
The MP18021 is a high frequency, 100V half
bridge N-channel power MOSFET driver. Its low
side and high side driver channels are
independently controlled and matched with less
than 5ns in time delay. Under voltage lock-out on
both high side and low side supplies force their
outputs low in case of insufficient supply. The
integrated bootstrap diode reduces external
component count.

MP18021―100V HIGH FREQUENCY HALF-BRIDGE GATE DRIVER
PIN FUNCTIONS
Pin # Name Description
1
VDD
Supply input. This pin supplies power to all the internal circuitry. A decoupling capacitor to
ground must be placed close to this pin to ensure stable and clean supply.
2
BST
Bootstrap. This is the positive power supply for the internal floating high-side MOSFET driver.
Connect a bypass capacitor between this pin and SW pin.
3 DRVH Floating driver output.
4 SW Switching node.
5 INH Control signal input for the floating driver.
6 INL Control signal input for the low side driver.
VSS,
7 Exposed Chip ground. Connect to Exposed pad to VSS for proper thermal operation.
