The TPS2043 and TPS2053 triple power distribution switches are triple channel power switches, using 135-mΩ N-channel MOSFET, support 5-V and 3-V logic, with internal charge pump, support 2.7-V input voltage, short circuit protection current is 500 mA, overcurrent protection current is 200 mA.
The TPS2043 and TPS2053 are triple N‑channel MOSFET high‑side power switches designed for heavy capacitive loads and short‑circuit conditions. Each channel provides up to 0.5 A continuous current, features over‑current and thermal protection, and can be enabled by logic‑level inputs compatible with 2.7 V–5.5 V supplies.
The device includes an internal charge pump, a fast driver with typical 2.5 ms rise time, undervoltage lockout, and a dual‑threshold thermal trip. It is offered in a 16‑pin SOIC package and operates over an ambient temperature range of –40 °C to 85 °C. Detailed electrical characteristics, mechanical dimensions, and packaging options are provided for design integration.
