UCC27523D 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 | Channel A enable input; high enables OUTA, low disables OUTA independent of INA state; floating enables output |
| 2 | INA | input | Channel A inverting input with TTL/CMOS thresholds (1.0-1.4V low, 1.9-2.3V high) and 0.9V hysteresis; output held low when input floating |
| 3 | GND | power_in | Ground reference; all signal levels measured with respect to this pin |
| 4 | INB | input | Channel B inverting input with TTL/CMOS thresholds (1.0-1.4V low, 1.9-2.3V high) and 0.9V hysteresis; output held low when input floating |
| 5 | OUTB | output | Channel B output; 5A peak source/sink current; rise time 7-18 ns, fall time 6-10 ns; swings GND to VDD |
| 6 | VDD | power_in | Auxiliary power supply input; 4.5-18V operating range with 4.2V UVLO on-threshold and 0.3V hysteresis |
| 7 | OUTA | output | Channel A output; 5A peak source/sink current; rise time 7-18 ns, fall time 6-10 ns; swings GND to VDD |
| 8 | ENB | input | Channel B enable input; high enables OUTB, low disables OUTB independent of INB state; floating enables output |
