The TPS25221 is intended for applications where heavy capacitive loads and short circuits may be encountered. The programmable current-limit threshold maybe set between 275 mA and 2.7 A (typical) using an external resistor. I_LIMIT accuracy as tight as ±6% can be achieved at the higher current-limit settings. Power-switch rise and fall times are controlled to minimize current surges during turn on and turn off.

When a load attempts to draw current exceeding the programmed I_LIMIT the internal FET enters constant current mode in order to keep I_LOAD at or below I_LIMIT. The FAULT output will assert low during over-current conditions after the built in de-glitch time.

TPS25221DBVEVM-018 — TPS25221 Evaluierungsmodul für einstellbaren strombegrenzten USB-Leistungsschalter

The TPS25221DBVEVM-018 is an evaluation module (EVM) for Texas Instrument's family of power-distribution switches with adjustable current-limit. This EVM operates over a 2.5 V to 5.5 V range. An onboard jumper sets the output current-limit to either 1.3 A or 2.6 A. Test points provide convenient (...)
