© 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 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.

increases, the average Vcp_out level decreases. For most of the applications a typical value of 33nF is recommended. The following figure is the simplified Ccp_out current and voltage waveforms. Figure 11. Simplified Ccp_out Current and Voltage Waveforms Ccp=33nF, Ccp_out=470nF and CLR_OUT=470nF. These values give a typical 100mV voltage ripple on Vcp_out and VLR_OUT with Qg=50nC. provided by a shunt resistor, as shown in figure 13. Typically shunt resistivity is dimensioned as low as possible (25mOhm/10A). The maximum A.O.P output voltage is 5V. Therefore a gain of 10 sets the maximum drop voltage on the sensing resistance at 500mV. Freescale Semiconductor, Inc.

If the O/UV protection is activated the outputs are driven low, in order to switch off the FETs. the circuitry against temperature damage by blocking the output drives.
