Description:
The ADP3410 is a dual MOSFET driver optimized for driving two N-channel FETs that are the two switches in the nonisolated synchronous buck power converter topology.
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 ADP3410 has several protection features: overlapping drive prevention (ODP), undervoltage lockout (UVLO) with performance specified at very low VCC levels, and overvoltage protection (OVP) that can be used to monitor either the input or output.
Additional features include: programmable transition delay, a synchronous drive override control pin, a synchronous drive status monitor and, in conjunction with exiting from the UVLO mode, a VCC Good (VCCGD) signal capable of driving a 10 umA load.
The quiescent current, when the device is disabled, is less than 10 umA.
