DPS1113

Description

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, and output voltage
ramping up. The fast role swap function which complies to the
requirement defined in the USB Power Delivery Specification Release
3.0, V1.0a is implemented.

This device is designed to operate between 4.5V and 5.5V. It 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 overvoltage protection, 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.

The DPS1113 is housed in the low-profile and space-saving VQFN4040-
17 package which is manufactured with environmentalfriendly
material.
