The NX5P2090 is an advanced power switch for USB OTG applications. It includes under-voltage and over-voltage lockout, over-current, over-temperature, reverse bias and in-rush current protection circuits. These are designed to automatically isolate a VBUS OTG voltage source from a VBUS interface pin when a fault occurs. The device features two power switch terminals, one input (VINT) and one output (VBUS); a current limit input (ILIM) for defining the over-current and in-rush current limit;
The NXP NX5P2090 is an advanced logic-controlled high-side power switch specifically designed for USB On-The-Go (OTG) applications. It features a wide supply voltage range from 3 V to 5.5 V and can tolerate up to 30 V on the VBUS pin. The device includes two power switch terminals, one input (VINT) and one output (VBUS), along with an enable input (EN) for control.
| Supply voltage range | 3 V to 5.5 V |
|---|---|
| VBUS tolerance | 30 V |
| Maximum continuous current | 2 A |
| ON resistance (typical) | 100 mΩ at 4.0 V |
| Low-power mode ground current | 20 µA typical |
| Control logic voltage | 1.8 V |
| Operating temperature range | -40 °C to +85 °C |
It is designed for USB OTG applications.
It uses an open-drain fault output (FAULT) that indicates when a fault has occurred.
The device enters low-power mode, disabling all protection circuits except under-voltage lockout.
