Product Overview
LTC1981 is a low-power, self-contained N-channel MOSFET driver. An internal voltage tripler allows gates to be driven without the use of any external components. Low quiescent current and low shutdown current (under 1µA) make this parts ideal for battery and other power constrained systems. The wide input voltage range accommodates a variety of battery/input configurations. Gate drive is internally clamped to 7.5V providing protection to the external MOSFET gate. The MOSFETs can be driven in either high side or low side mode. It is widely used in application such as cellular telephones, portable POS terminal, handheld battery powered equipment etc.
- Internal voltage triplers produce high side gate drive for logic level FETs
- Supply current is 17µA typical at (GATE 1 and GATE 2 outputs high)
- Operating supply voltage range is 1.8V to 5.5V
- Gate drive outputs driven to ground during shutdown
- Gate drive ready output
- Ultrasmall application circuit
- GDR hysteresis is 2% typical
- Charge pump oscillator frequency is 600KHz
- Operating temperature is -40°C to 85°C
- Package style is 5-lead plastic SOT-23
