LM3526MX-L from Texas Instruments, 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 | ENA | input | Enable input for Port A with active-low logic for LM3526-L variant, output enabled when input ≤ 0.8V and disabled when input ≥ 2.4V |
| 2 | FLAG A | tri_state | Fault flag A output, open-drain active-low output that sinks current when overcurrent, UVLO, or thermal shutdown condition is detected with 1ms delay |
| 3 | FLAG B | tri_state | Fault flag B output, open-drain active-low output that sinks current when overcurrent, UVLO, or thermal shutdown condition is detected with 1ms delay |
| 4 | ENB | input | Enable input for Port B with active-low logic for LM3526-L variant, output enabled when input ≤ 0.8V and disabled when input ≥ 2.4V |
| 5 | OUT B | output | Switch output for Port B, high-side MOSFET output with 140mΩ max on-resistance and 500mA max continuous current rating |
| 6 | GND | power_in | Ground reference for all circuit operation |
| 7 | IN | power_in | Supply input with 2.7V to 5.5V operating range, providing power to control circuitry and MOSFET source |
| 8 | OUT A | output | Switch output for Port A, high-side MOSFET output with 140mΩ max on-resistance and 500mA max continuous current rating |
