Description

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 of MC33253 include a cross conduction suppression circuit, which, if enabled, prevents the external power FETs from being on at the same time.

The drive outputs of MC33253 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 of MC33253 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 of MC33253 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 of MC33253 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 MC33253 could be used to feedback information from the output load to the external MCU.
