NX5P2553 Overview
Description
The NX5P2553 is a precision adjustable current-limited power switch. The device includes undervoltage lockout, overtemperature, and reverse bias protection circuits designed to isolate the switch terminals when a fault condition occurs.
Key Features
- Wide supply voltage range from 2.5 V to 5.5 V
- ISW maximum 1.5 A continuous current
- 6 % current-limit accuracy at 1.8 A (typical)
- Meets USB current-limiting requirements
- Adjustable current limit from 85 mA to 1800 mA (typical)
- Constant current mode in overcurrent situation
- Overtemperature protection
- Very low ON resistance: 95 m (typical) for TSOP6 package
- Fast short-circuit switch-off response (2.0 s typical)
- ILIM short detection
