The DPS1133 is part of a family of power switches optimized for the 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 with the requirements defined in the USB Power Delivery Specification Release 3.0, V1.0a is implemented.
This device is designed to operate between 4.5V and 24V. 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 DPS1133 is housed in the low-profile and space-saving V-QFN4040-17 package which is manufactured with environmental-friendly material.
