FEATURES
s s s s s s s s s s No External Components Required Internal Voltage Triplers Produce High Side Gate Drive for Logic Level FETs Ultralow Power: 10µA Per Driver ON Current (LTC1982) 20µA ON Current (LTC1981) <1µA Shutdown Current VCC Range: 1.8V to 5V Gate Drive Outputs Driven to Ground During Shutdown Gate Drive Outputs Internally Clamped to 7.5V Max “Gate Drive Ready” Output (LTC1981) Ultrasmall Application Circuit 5-Pin SOT-23 Package (LTC1981) 6-Pin SOT-23 Package (LTC1982) 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. Low quiescent current and low shutdown current (under 1µA) make these parts ideal for battery and other power constrained systems. The wide input voltage range accommodates a variety of battery/input configurations.
