TECHNICAL DATA

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.

CASE 751F-05

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. A built-in single supply operational amplifier could

be used to feedback information from the output load to the external

MCU.
