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.
Features and benefits
