Frequently Asked Questions
What is the TPS2553DRVT-1 and what does it do?
The TPS2553DRVT-1 is a precision-adjustable current-limited power distribution switch from Texas Instruments that protects downstream circuitry by limiting current to a user-defined threshold set via an external resistor, with a maximum input voltage of 5.5V and current limit up to 2A.
How is the current limit set on the TPS2553DRVT-1?
The current limit on the TPS2553DRVT-1 is set by connecting an external resistor to the ILIM pin, allowing designers to precisely program the overcurrent threshold from a low value up to approximately 2A to match the specific requirements of the connected load or USB standard.
What protection features does the TPS2553DRVT-1 include?
The TPS2553DRVT-1 integrates thermal shutdown to prevent overheating, an active-low fault flag output to signal overcurrent or thermal fault conditions to the host controller, and automatic retry or latch-off behavior, providing comprehensive protection for downstream loads in USB and embedded power distribution systems.
What applications is the TPS2553DRVT-1 best suited for?
It is best suited for USB port power switching in notebooks and hubs, multi-rail embedded power management, portable device charging protection, and any application where a reliable, resettable current-limited switch with fault reporting is needed to protect sensitive electronics from overcurrent damage.
