LTC1981/LTC1982

Single and Dual Micropower

High Side Switch Controllers

in SOT-23

FEATURES

DESCRIPTIO

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

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 quies-

cent 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 ac-

commodates a variety of battery/input configurations.

Gate drive is internally clamped to 7.5V providing protec-

tion to the external MOSFET gate. The MOSFETs can be

driven in either high side or low side mode.

The LTC1981 single driver version also includes a gate

drive ready pin and twice the drive current capacity of the

dual driver LTC1982.

The LTC1981 is available in a 5-pin SOT-23. The LTC1982

is available in a 6-pin SOT-23.
