Freescale Semiconductor, Inc. Order Number: MC33253/D Rev 3, 03/2001 Advance Information MC33253 55 VOLTS SEMICONDUCTOR TECHNICAL DATA Full Bridge Pre-Driver 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 suppressio
More View n 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 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. • VCC Operating Voltage Range from 5.5 V up to 55 V • VCC2 Operating Voltage Range from 5.5 V up to 28 V • Automotive Temperature Range -40°C to 125°C • 1A Pulse Current Output Driver • Fast PWM Capability • Built-In Charge Pump • Cross Conduction Suppression Circuit Freescale Semiconductor, Inc...
