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 ADP3416 includes overlapping drive protection (ODP) to prevent shoot-through current in the external MOSFETs. The ADP3416 is specified over the mercial temperature range of 0°C to 70°C and is available in an 8-lead SOIC package. 7V D1 VCC 12V CBST DRVH Q1 DELAY 1V DRVL 1V PGND Q2 Figure 1.
