LTC1982ES6

Single and Dual Micropower High Side Switch Controllers in SOT-23

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.
