LM3526M-H from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | ENA | input | Logic-compatible enable input for switch A; for the LM3526-H variant the switch is off when EN is 0.8V or less and on when EN is 2.4V or more. |
| 2 | FLAG A | output | Active-low, open-drain fault flag output for port A that indicates overcurrent, UVLO or thermal shutdown. |
| 3 | FLAG B | output | Active-low, open-drain fault flag output for port B that indicates overcurrent, UVLO or thermal shutdown. |
| 4 | ENB | input | Logic-compatible enable input for switch B; for the LM3526-H variant the switch is off when EN is 0.8V or less and on when EN is 2.4V or more. |
| 5 | OUT B | power_out | Output of the high-side P-channel power switch for port B. |
| 6 | GND | power_in | Ground reference for the device. |
| 7 | IN | power_in | Supply input to the power switch and supply voltage for the IC, operating from 2.7V to 5.5V. |
| 8 | OUT A | power_out | Output of the high-side P-channel power switch for port A. |
