LM3526MX-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 | Enable input for port A; active-high logic for LM3526-H variant: switches ON when ENA ≥ 2.4V, OFF when ENA ≤ 0.8V; input leakage ±0.5 µA maximum. |
| 2 | FLAG A | tri_state | Open-drain active-low fault flag output for port A; indicates overcurrent, under-voltage lockout (UVLO), or thermal shutdown condition with 1 ms delay; can sink 10 mA. |
| 3 | FLAG B | tri_state | Open-drain active-low fault flag output for port B; indicates overcurrent, under-voltage lockout (UVLO), or thermal shutdown condition with 1 ms delay; can sink 10 mA. |
| 4 | ENB | input | Enable input for port B; active-high logic for LM3526-H variant: switches ON when ENB ≥ 2.4V, OFF when ENB ≤ 0.8V; input leakage ±0.5 µA maximum. |
| 5 | OUT B | output | High-side P-channel MOSFET switch output for port B; on-resistance 100 mΩ typical at 5V and 500 mA; maximum continuous output current 0.5 A; short-circuit output current 1 A nominal. |
| 6 | GND | power_in | Ground connection for the integrated circuit. |
| 7 | IN | power_in | Power supply input for high-side switches and control circuitry; operating voltage range 2.7V to 5.5V; under-voltage lockout (UVLO) threshold 1.8V typical. |
| 8 | OUT A | output | High-side P-channel MOSFET switch output for port A; on-resistance 100 mΩ typical at 5V and 500 mA; maximum continuous output current 0.5 A; short-circuit output current 1 A nominal. |
