The TPS2048 and TPS2058 quad power-distribution switches are intended for applications where heavy capacitive loads and short circuits are likely.
The TPS2048 and TPS2058 are four‑channel high‑side MOSFET power‑distribution switches designed for hot‑plug and heavy‑capacitive load applications. Each channel includes a charge‑pump‑driven driver, over‑current (OCx) logic output, thermal shutdown, undervoltage lockout, and a 2.5 ms typical rise time.
Typical applications include notebook, desktop, and portable PCs, monitors, keyboards, scanners, printers, digital cameras, phones, and PBXs. The devices are supplied in a 16‑pin SOIC package and operate over an ambient temperature range of –40 °C to 85 °C.
| Operating voltage range | 2.7 V to 5.5 V |
|---|---|
| Continuous current per channel | 250 mA |
| Standby supply current (no load) | < 20 mA |
| Package type | 16‑pin SOIC |
| Ambient temperature range | –40 °C to 85 °C |
The typical rise time is about 2.5 ms.
The device draws less than 20 mA in standby (no‑load) condition.
