TPS25221
- 2.5-V to 5.5-V VOPERATING
- Pin-to-Pin with TPS2553
- 2-A ICONT_MAX
- 0.275-A to 2.7-A Adjustable ILIMIT (±6.5% at 1.7 A)
- 70-mΩ (typical) RON
- 1.5-µs Short Circuit Response
- 8-ms Fault Reporting Deglitch
- Reverse Current Blocking (when disabled)
- Built-In Soft Start
- UL 60950 and UL 62368 Recognition
- 15-kV ESD Protection per IEC 61000-4-2 (with external capacitance)
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. ILIMIT 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 ILIMIT the internal FET enters constant current mode in order to keep ILOAD at or below ILIMIT. The FAULT output will assert low during over-current conditions after the built in de-glitch time.

TPS25221DBVEVM-018 — 조정 가능한 전류 제한 USB 전원 스위치를 위한 TPS25221 평가 모듈
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 (...)
