0.5 V to 1.0 V, 1.5 A peak, 11 mΩ, load switch
NPS1000 is a low voltage, single-channel load switch with a low RDS,ON (11 mΩ) to minimize IR drop and power loss. It supports up to 0.6 A RMS current and a peak current of 1.5 A.
The switch is controlled by an EN input which is compatible with 1.2 V logic levels. When the load switch is enabled, the internal switch charges the output capacitor with a controlled inrush current. When the switch is disabled, an 8 Ω on-chip resistor discharges the output to ground and keeps it from floating.
The IC is powered from a separate BIAS pin which is rated for 2.3 V to 5.0 V 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 turns on to discharge the output capacitor. The load switch can be enabled again by toggling the EN pin.
NPS1000 is available in an ultra-small, space saving, wafer level chip-scale package; 8 bumps; 1.42 mm × 0.72 mm × 0.465 mm body and is characterized for operation over junction temperature range of –?40 °C to 105 °C.

描述 The NEVB-NPS1000 is a two-layer PCB containing the NPS1000 load switch device. The VIN and VOUT connections to the device and the PCB layout routing provides a low-resistance pathway into and out of the device under test. Test point connections allow the EVB user to control the device with userdefined test conditions a nd make accurate device measurements.

How does it work?
The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
