channel is floating above ground.

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.

operation at abnormal supply voltages. Under fault, these functions force

the driver stages into off state.

outputs. The input hysteresis makes the output switching time

independent of the input transition time.

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.

The MC33253 is a full bridge driver including integrated charge

The high and low side drivers include a cross conduction suppression

The drive outputs are capable to source and sink 1 A pulse peak

An under- and over-voltage protection prevents erratic system

The logic inputs are compatible with standard CMOS or LSTTL

The global enable logic signal can be used to disable the charge

A linear regulator provides a maximum of 15.5V to supply the low

Operating Voltage Range from 5.5 V up to 55 V

Operating Voltage Range from 5.5 V up to 28 V
