TPS2554
Overview
The TPS2554/55 power-distribution switches are intended for applications where precision current limiting is required or heavy capacitive loads and short circuits are encountered. These devices offer a programmable current-limit threshold between 500 mA and 2.5 A (typ) via an external resistor.
- 2 Meets USB Current-Limiting Requirements
- Adjustable Current Limit, 500 mA to 2.5 A (typ)
- Two Independently-Settable, Current-Limit Thresholds
- Fast Overcurrent Response - 1.5 μs (typ)
- 73-mΩ High-Side MOSFET
- 3.8-μA Maximum Standby Supply Current
- PowerPAD™ Thermal Management
- Automatic Output Discharge when Disabled
- Both High-Enable (TPS2554) and Low-Enable (TPS2555) Versions Available
