DPS1113
5V/3A 1-CH POWER SWITCH WITH FAST ROLE SWAP
Description
Pin Assignments
The DPS1113 is part of a family of power switches optimized for USB
Power Delivery and other hot-swap applications. Through the analog
interface, exception status is reported and several functions can be
programmed: current limit, Overvoltage Protection (OVP), and output
voltage ramping up. The device implements the fast role-swap
function, which complies with the USB Power Delivery Specification
Release 3.0, V1.0a requirement.

This device operates between 4.5V and 5.5V and offers fast short-
circuit response time to ensure system robustness. The integrated
port-discharge function allows the voltage levels at the input and
output ports to be discharged to meet the requirements of the USB
Power Delivery Specification. Comprehensive fault detection and
recovery mechanisms are provisioned to enable applications, which
are subjected to heavy capacitive loads and the risk of short circuit.
These mechanisms include reverse voltage & current blocking, input
OVP, output overcurrent, short-circuit protection and overtemperature
shut-down. In addition, the rise time of output voltage can be adjusted
to minimize in-rush current and to ensure system stability. Before any
exception condition is notified via the low-active FAULTB signal,
deglitch of 7ms is applied to prevent false triggering.
