描述 Description

The NX5P3090 is a precision adjustable current-limited power switch forUSB PD application. The device includes under voltage lockout, over-temperatureprotection, and reverse current protection circuits to automatically isolate the switchterminals when a fault condition occurs. The 29V tolerance on VBUS pin ensures thedevice is able to work on a USB PD port; a current limit input (ILIM) pin defines theover-current limit threshold; an open-drain fault output (FAULT) indicates when a faultcondition has occurred.
The over-current limit threshold can be programmed from 400 mA to3.3 A, using an external resistor between the ILIM pin and GND pin. In the over currentcondition, the device will clamp the output current to the value set by ILIM and keepthe switch on while assert the FAULT flag. To minimize current surges during turn on andturn off, the device has built in soft start which controls the power switch rise andfall time.
Surge protection has been integrated in the device to enhance system robustness. Theenable input includes integrated logic level translation making the device compatiblewith lower voltage processors and controllers.
NX5P3090 is offered in a 12 bump 1.35 × 1.65 mm, 0.4 mm pitchWLCSP package.
