DESCRIPTION
This is EV board documentation for
MPQ18021A. The MPQ18021A 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 a time delay of less than 5ns.
Under-voltage lockout 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.
This demo board is configured to a buck
converter. INH and INL are independent signals
of each other. For simplicity, the user only need
to supply a PWM signal to this demo board and
the on-board circuitry will generate INH and INL
signals with proper dead time. In a real system,
the controller will have to take care of dead time
adjustment.
