NX20P3483UK USB PD and Type-C high voltage sink/source combo switch with protection Rev. 2 4 March 2019 Product short data sheet 1. General description The NX20P3483UK is a product with combined multiple power switches and an LDO for USB PD application. The device includes a bidirectional high voltage power switch which supports both 20V sink and 6V source a 5V power switch for source and a 100mA LDO provides power supply for dead battery operation. The high voltage power switch has 29V DC tolerance, and is able to sink up to 5A at maximum of 20V and source up to 3.4A at maximum of 6V. When it is configured as a high voltage sink switch, the path has overvoltage protection and reverse current protection features. While it is configured as high voltage source switch, the adjustable overcurrent limit circuit is integrated. The 5V power switch has an adjustable overcurrent limit, ideal diode feature and short circuit protection. The maximum current capability is 3.4A. It supports fast role swap for USB PD3.0 application. A VBUS discharge circuit is integrated according to USB PD VBUS discharging requirement. To minimize inrush current during normal startup, turn on slew rate control has been built in for all power switches. Over temperature protection is also equipped to automatically isolate the switch terminals when the device is overheated. 2 The device is controlled through an I C-bus interface, allowing the host to configure 2 switches and program different specified parameters according to an I C register map. The NX20P3483UK is offered with WLCSP42 package: 0.4mm pitch, 2.51 x 2.91 x 0.525mm, 0.4mm pitch. 2.
