Advance Information
Full Bridge Pre-Driver
The MC33883 is a full bridge pre-driver including integrated charge
pump, two independent high and low side driver channels.
The drive outputs are capable to source and sink 1 A pulse peak
current. The low side channel is referenced to ground, the high side
channel is floating above ground.
A linear regulator provides a maximum of 16.5V to supply the low
side gate driver stages. The high side driver stages are supplied with a
10Vtypical charge pump voltage. Such built-in feature, associated to
external capacitor provides a full floating high side drive.
An under- and over-voltage protection prevents erratic system
operation at abnormal supply voltages. Under fault, these functions force
the driver stages into off state.
The logic inputs are compatible with standard CMOS or LSTTL
outputs. The input hysteresis makes the output switching time
independent of the input transition time.
The global enable logic signal can be used to disable the charge
pump and all the bias circuit. The net advantage is the reduction of the
quiescent supply current to under 10µA. To wake up the circuit, 5 V has
to be provided at G_EN.
