Dual high-side gate driver controls low-cost N-channel MOSFETs for high-side switching applications. The device operates from a 4.5 V to 18 V supply and uses an internal charge pump to drive MOSFET gates above the positive supply without external components. Micropower operation provides 8 µA standby current and 85 µA operating current per driver at 5 V, with TTL/CMOS-compatible inputs and on-chip overcurrent sensing using a 100 mV drain-sense threshold. It is offered in 8-pin PDIP and 8-pin SO package options.
