Overview: ADP3121 Dual Bootstrapped, 12 V
MOSFET Driver with Output
Disable
The ADP3121 is a dual, high voltage MOSFET driver optimized for driving two N−channel MOSFETs, the two switches in a non−isolated synchronous buck power converter. Each driver is capable of driving a 3000 pF load with a 20 ns propagation delay and a 15 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 ADP3121 includes overlapping drive protection to prevent shoot−through current in the external MOSFETs.
The OD pin shuts off both the high−side and the low−side MOSFETs to prevent rapid output capacitor discharge during system shutdown.
The ADP3121 is specified over the mercial temperature range of 0°C to 85°C and is available in 8−lead SOIC_N and 8−lead LFCSP packages.
