Nexperia NPS100x Load Switches

Nexperia NPS100x Load Switches are low-voltage, single-channel load switches with a low RDSON (11mΩ) to reduce IR drop and power loss. The NPS1000 supports up to 0.6A RMS current and a peak current of 1.5A. The switches are controlled by an EN input compatible with 1.2V logic levels. When the load switches are enabled, the internal switch charges the output capacitor with a controlled inrush current. When the switches are disabled, an 8Ω on-chip resistor discharges the output to ground, preventing it from floating.

The Nexperia NPS1000 Load Switches are powered by a separate BIAS pin, rated for 2.3V to 5.0V operation. NPS1000 has an over-temperature protection that latches the device OFF when the internal junction temperature is above the set point (Tth(OTLO)). At this time, the internal switch is turned off, and the output discharge element is turned on to discharge the output capacitor. The load switches can be enabled again by toggling the EN pin.

The NPS1000 is offered in an ultra-small, space-saving, wafer-level chip-scale package with eight bumps, a 1.42mm × 0.72mm × 0.465mm body, and is developed for operation over a junction temperature range of -40°C to +105°C.
