NX3P Power Switches NXP NX3P Power Switches integrate reverse-current/voltage protection, over-voltage protection, over-current protection, and over-temperature protection, actively protecting it and the components it supplies, when a system-fail event is detected. These NXP load switches offer integrated slew-rate control that reduces inrush current associated with system start-up, while the ILIM feature limits the maximum switch current. Equipped with a low-threshold logic enable input, NX3P devices can be used with both new and legacy controllers. Under-voltage and over-voltage lock-out ensure these switches remain disabled until issues are removed before resuming normal operation.
