DPS1113中文资料5.5V/3.5A 1-Ch Power Switch With Fast Role Swap数据手册Diodes规格书

描述 Description

The DPS1113 is part of a family of power switches optimized for USBPower Delivery and other hot-swap applications. Through the analoginterface, exception status is reported and several functions can beprogrammed: current limit, overvoltage protection, and output voltageramping up. The fast role swap function which complies to therequirement defined in the USB Power Delivery Specification Release3.0, V1.0a is implemented.This device is designed to operate between 4.5V and 5.5V. It offersfast short-circuit response time to ensure system robustness. Theintegrated port-discharge function allows the voltage levels at theinput and output ports to be discharged to meet the requirements ofthe USB Power Delivery Specification. Comprehensive fault detectionand recovery mechanisms are provisioned to enable applicationswhich are subjected to heavy capacitive loads and the risk of shortcircuit. These mechanisms include: reverse voltage & currentblocking, input overvoltage protection, output overcurrent, short-circuitprotection and overtemperature shut-down. In addition, the rise timeof output voltage can be adjusted to minimize in-rush current and toensure system stability. Before any exception condition is notified viathe low-active FAULTB signal, deglitch of 7ms is applied to preventfalse triggering.The DPS1113 is housed in the low-profile and space-saving VQFN4040-17 package which is manufactured with environmentalfriendlymaterial.
