Each of the drivers is capable of driving a 3000 pF load with a 20 ns propagation delay and a 30 ns transition time. One of the drivers can be bootstrapped, and is designed to handle the high-voltage slew rate associated with “floating” high-side gate drivers. The ADP3414 includes overlapping drive protection (ODP) to prevent shoot-through current in the external MOSFETs. The ADP3414 is specified over the commercial temperature range of 0°C to 70°C and is available in an 8-lead SOIC package. 7V D1 12V VCC ADP3414 BST CBST DRVH IN Q1 SW DELAY +1V DRVL 1V PGND Q2 Figure 1.
