TECHNICAL DATA
Motorola, Inc., 2001. All rights reserved.
The MC33253 is a full bridge driver including integrated charge
pump, two independent high and low side driver channels.
The high and low side drivers include a cross conduction suppression
circuit, which, if enabled, prevents the external power FETs from being on
at the same time.
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 15.5V to supply the low
side gate driver stages. The high side driver stages are supplied with a
10V 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 10
A. To wake up the circuit, 5 V has to
be provided at G_EN. A built-in single supply operational amplifier could
be used to feedback information from the output load to the external
MCU.
