STMicroelectronics ST890
The ST890 device is a low voltage, P-channel MOSFET power switch intended for high-side load switching applications. The switch operates with inputs from 2.7 V to 5.5 V, making it ideal for both 3 V and 5 V systems. The internal current limiting circuitry protects the input supply against overload.| Part No. | ST890 |
