NX5P2553

Precision adjustable current-limited power switch

10. Recommended operating conditions

[1]

Current-limit threshold resistor range from ILIM to GND.

11. Thermal characteristics

[1]

multi-layer PCBs, the second layer should be used to create a large heat spreader area below the device. Avoid using solder-stop

varnish under the device.
