MP1924―100V, 4A HIGH FREQUENCY HALF-BRIDGE GATE DRIVER
APPLICATION
The input signals of INH and INL can be
controlled independently. If both INH and INL
control the high-side MOSFET and low-side
MOSFET of the same bridge, then users must
avoid shoot through by
setting sufficient dead time between INH and INL
low, and vice versa. See Figure 3 below. Dead
time is defined as the time interval between INH
low and INL low.
