TPS2115APW

TPS2115APW Description

The TPS2115APW from Texas Instruments is a high-performance source selector switch designed for seamless power management in handheld and mobile devices. This 2:1 input-to-output ratio IC integrates internal switches, enabling automatic or manual selection between two power sources with minimal voltage drop. Operating within a 2.8V to 5.5V supply range, it delivers up to 1.25A of continuous output current while consuming just 55 µA of quiescent current, making it ideal for battery-powered applications. The device features 1 ms ON and 5 ms OFF delay times, ensuring smooth transitions between power sources without disrupting downstream circuitry. Packaged in an 8-pin TSSOP tube, it is RoHS3 compliant and rated MSL 1 (Unlimited) for moisture sensitivity.
