Mô tả chung
The ET20171H is a current limit N-Channel MOSFET power switch. It is designed to protect circuitry on the output from transients on the input. It also protects the input from undesired shorts and transients coming from the output.
The current limit magnitude is controlled by an external resistor from ILIMIT to GND. It is fixed 0.73A when ILIMIT is floating. Programmable soft-start time controls the slew rate of the output voltage during the start-up time. It can be controlled by the DV/DT pin setting.
The output voltage will be clamped at 6.1V when the input voltage exceeds 6.1V.
In the event device temperature (TJ ) exceeds TSD(155°C), The ET20171H device remains off for 100ms until the temperature drops to TSD -TSD_HYS (30°C), after which it attempts to restart. This ON and OFF cycle continues until fault is cleared.
