TABLE 3-1: PIN FUNCTION TABLE 3.1 Supply Input (VDD) The VDD input is the bias supply for the MOSFET driver and is rated for 4.5V to 18V with respect to the ground pin. The VDD input should be bypassed to ground with a local ceramic capacitor. The value of the capacitor should be chosen based on the capacitive load that is being driven. A minimum value of 1.0 μF is suggested. 3.2 Control Input The MOSFET driver input is a high-impedance, TTL/CMOS-compatible input. The input also has 300 mV of hysteresis between the high and low thresholds that prevents output glitching even when the rise and fall time of the input signal is very slow. 3.3 CMOS Push-Pull Output The MOSFET driver output is a low-impedance, CMOS, push-pull style output capable of driving a capacitive load with 12A peak currents. The MOSFET driver output is capable of withstanding 1.5A peak reverse currents of either polarity. 3.4 Ground The ground pins are the return path for the bias current and for the high peak currents that discharge the load capacitor. The ground pins should be tied into a ground plane or have very short traces to the bias supply source return. 3.5 Exposed Metal Pad The exposed metal pad of the 6x5 DFN package is not internally connected to any potential. Therefore, this pad can be connected to a ground plane or other copper plane on a Printed Circuit Board (PCB) to aid in heat removal from the package. 3.6 Metal Tab The metal tab of the TO-220 package is connected to the VDD potential of the device. This connection to VDD can be used as a current carrying path for the device.
