FEATURES  
DESCRIPTIO  
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-  
centcurrenttodropto10µAperdriver(20µAforLTC1981)  
once the gates are charged.  
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  
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.  
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 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.  
“Gate Drive Ready” Output (LTC1981)  
Ultrasmall Application Circuit  
5-Pin SOT-23 Package (LTC1981)  
6-Pin SOT-23 PaUckage (LTC1982)  
The LTC1981 single driver version also includes a gate  
drive ready pin and twice the drive current capacity of the  
dual driver LTC1982.  
APPLICATIO S  
Cellular Telephones  
Portable POS Terminal  
Handheld Battery Powered Equipment  
The LTC1981 is available in a 5-pin SOT-23. The LTC1982  
is available in a 6-pin SOT-23.
