1 / 8 page LTC1981/LTC1982 1 APPLICATIO S DESCRIPTIO 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 µAperdriver(20µAforLTC1981) once the gates are charged. Low quiescent current and low shutdown current (under 1 µA) 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. s Cellular Telephones s Portable POS Terminal s Handheld Battery Powered Equipment , LTC and LT are registered trademarks of Linear Technology Corporation. s No External Components Required s Internal Voltage Triplers Produce High Side Gate Drive for Logic Level FETs s Ultralow Power: 10 µA Per Driver ON Current (LTC1982) 20 µA ON Current (LTC1981) <1 µA Shutdown Current s VCC Range: 1.8V to 5V s Gate Drive Outputs Driven to Ground During Shutdown s Gate Drive Outputs Internally Clamped to 7.5V Max s “Gate Drive Ready” Output (LTC1981) s Ultrasmall Application Circuit s 5-Pin SOT-23 Package (LTC1981) s 6-Pin SOT-23 Package (LTC1982) Single and Dual Micropower High Side Switch Controllers in SOT-23 VCC GATE SHDN GND GDR LTC1981 LOAD + 10 µF GATE DRIVE READY SHDN VCC 1.8V TO 5.0V 54 123 1981/82 TA01 100k Q1 Si3442DV VCC GATE 1 GATE 2 SHDN 1 SHDN 2 GND LTC1982 LOAD 1 LOAD 2 + 10 µF SHDN 1 SHDN 2 VCC 1.8V TO 5.0V 654 123 1981/82 TA02 Q1 1/2 Si6925DQ Q2 1/2 Si6925DQ TYPICAL APPLICATIONS Single High Side Switch Controller Dual High Side Switch Controller |
