SP2525A-1EN-L from MaxLinear, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | EN | input | Enable input. Active-high on the SP2525A-1 variant (SP2525A-1EN-L). Logic-low threshold ≤0.8V (typ 1.7V), logic-high threshold ≥2.0V (typ 2.4V). Input tolerates up to 15V and draws ~0.01µA (1µA max). |
| 2 | FLG | output | Active-low, open-drain fault flag output. Pulled low to indicate output current limiting, thermal shutdown, or undervoltage lockout. Output resistance ~10Ω typ (25Ω max) at VIN=5V, IL=10mA; max sink current 50mA; requires external pull-up. |
| 3 | GND | power_in | Chip power ground. Reference for all internal circuitry. |
| 4 | NC | unconnected | Not internally connected. May be left floating or tied to GND for layout convenience. |
| 5 | IN | power_in | Power supply input and drain of the internal N-channel high-side MOSFET. Operates from +3.0V to +5.5V (7.0V absolute max). Pins 5 and 7 are internally the same IN node and should be tied together on the PCB; 0.1µF-1µF bypass capacitor from IN to GND recommended. |
| 6 | OUT | power_out | Switched power output - source of the internal N-channel MOSFET. Delivers 500mA continuous per channel with 70mΩ typ (100mΩ max) RDS(ON); current-limited at 0.6-1.25A (1.0A typ). Pins 6 and 8 are internally the same OUT node and should be tied together on the PCB. |
| 7 | IN | power_in | Second bond to the IN power supply node (drain of the internal high-side MOSFET). Tie to pin 5 on the PCB to carry the switch current and improve thermal performance. |
| 8 | OUT | power_out | Second bond to the OUT node (source of the internal high-side MOSFET). Tie to pin 6 on the PCB to carry the load current and improve thermal performance. |
