Description
TPS23880RTQR is a Texas Instruments device in the TPS23880 family. It is a dual high‑side protection switch designed for hot‑swap/surge protection of power loads. Key ideas:
- Dual channel: provides two protected power paths with current‑limiting and fault protection.
- Built‑in protection: overcurrent/short‑circuit protection, thermal shutdown, and fault/status reporting.
- Auto‑retry: faults automatically clear and the device attempts to restart.
- Applications: use in power‑supply front ends, telecom/industrial equipment, and other systems that require safe plug‑in and surge protection for loads.
- Packaging: RTQR indicates Tape & Reel packaging (and RoHS/compliant variant).
In short, TPS23880RTQR is a dual surge‑stopper/line protection device that helps protect loads and manage faults during power connection events. If you need exact electrical specs (voltage/current limits, timing, and pinout), consult the TI datasheet for the TPS23880 series.
