LM3526MX-H

Texas Instruments · Power Distribution Switches · SOIC-8

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.
