MC33253
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 patible 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.
