APPLICATIU
DESCRIPTIOU
FEATURES
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 10
μ
A per driver (20
μ
A for LTC1981)
once the gates are charged.
Low quiescent current and low shutdown current (under
1
μ
A) 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.
