SP2525A-1EN-L

MaxLinear · Supervisor and Reset ICs · SOIC-8

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.
