LTC1981ES5 Datasheet PDF - Linear Technology

DESCRIPTION

●The LTC® 1981/LTC1982 are low-power, self-contained N-channel MOSFET drivers. An internal voltage tripler

●allows gates to be driven without the use of any external components. Internal regulation circuitry allows quiescent current to drop to 10µA per driver (20µA for LTC1981) once the gates are charged.

●FEATURES

●■ No External Components Required
