PRODUCTION DATA
The devices are current-limited, power distribution switches using N-channel MOSFETs for applications where short-circuits or heavy capacitive loads are encountered. These devices have a minimum fixed current-limit threshold above 1.1A allowing for continuous operation up to 1A per channel. Overtemperature protection is an additional device shutdown feature. Each device incorporates an internal charge pump and gate drive circuitry necessary to drive the N-channel MOSFETs. The charge pump supplies power to the driver circuit and provides the necessary voltage to pull the gate of the MOSFET above the source. The charge pump operates from input voltages as low as 2.7V and requires little supply current. The driver controls the gate voltage of the power switch. The driver incorporates circuitry that controls the rise and fall times of the output voltage to provide "soft-start" and to limit large current and voltage surges.
