Features, Applications

The is a full bridge pre-driver including integrated charge pump, two independent high and low side driver channels. 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 16.5V to supply the low side gate driver stages. The high side driver stages are supplied with a 10Vtypical 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 10A. To wake up the circuit, 5 V has to be provided at G_EN.
