MP1907
The Future of Analog IC Technology
DESCRIPTION
The MP190 7 is a h igh frequency, 100V half
bridge N-channel power MOSFET driver. Its low
side and high side
driver c hannels ar e
independently controlled and match ed with le ss
than 5ns in time delay. Under-volt age lock-ou t
both high side and low side supplies force their
outputs low in case of insufficie nt supply. Both
outputs will remain low until a rising edge on
either inpu t is dete cted. The integrated
bootstrap d iode reduces external component
count.

PIN FUNCTIONS
Package
Pin #
Name
Description
1 VDD
Supply input. This pin su pplies power to all the internal circuitry. A decou pling capacitor to
ground must be placed close to this pin to ensure stable and clean supply.
2 NC No Connection.
3 BST
Bootstrap. This is the positive powe r sup ply for th e internal floating high-si de MOSFET
driver. Connect a bypass capacitor between this pin and SW pin.
4 DRVH Floating driver output.
5 SW Switching node.
6 EN On/off Control.
7 INH Control signal input for the floating driver.
8 INL Control signal input for the low side driver.
VSS,
9 Exposed Chip ground. Connect to Exposed pad to VSS for proper thermal operation.
