Nuvoton Technology Corp. introduces low RDSON with soft-start and output discharge power distribution switch– NCT3521U/U-2. The power switch provides continuous 2.0Amp output current, 80m-ohm RDSON and equips over current, short circuits, reverse current, reverse voltage protections and thermal shutdown which can secure the system from damage while power on/off shorted.

NCT3521U/U-2 is very suitable for computer LCD on/off power protection or other power distribution switch devices. It supports soft-start and shutdown output discharge functions which user can not only adjust application circuits timing slightly but also ease the rush current impact which induced by capacitance loading. Shutdown output discharge function can reset the output voltages to 0V when OFF. It avoids external circuitry from malfunction and makes system circuits design solid and highly reliable.

Product Package and Promotion

The NCT3521U is a SOT23-5 Green package ; NCT3521U-2 (with Soft-start pin) is a SOT23-6 Green package. Both are compliant with ROHS and halogen free standards. The products are in mass production and the demo board is also available for promotion.
