SL27523 from Slkor(SLKORMICRO Elec.), in a SOP-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: when pulled low OUTA is forced low, while high or floating it lets OUTA follow INA; TTL/CMOS compatible with a 24 V maximum input tolerance and a weak internal pull-up. |
| 2 | INA | input | Channel A gate-drive input, inverting on the SL27523 with an internal pull-up so OUTA goes low if the input floats; the datasheet gives a -5 V to 24 V absolute range and 0 V to 20 V recommended. |
| 3 | GND | power_in | Ground reference for the driver, the return for VDD and the gate-drive outputs. |
| 4 | INB | input | Channel B gate-drive input, inverting on the SL27523 with an internal pull-up so OUTB goes low if the input floats; the datasheet gives a -5 V to 24 V absolute range and 0 V to 20 V recommended. |
| 5 | OUTB | output | Channel B push-pull gate-drive output with 4 A peak source/sink current, swinging rail-to-rail between GND and VDD. |
| 6 | VDD | power_in | Supply pin with 4.5 V to 20 V recommended operation and 24 V absolute maximum; below the UVLO threshold the outputs are held low. |
| 7 | OUTA | output | Channel A push-pull gate-drive output with 4 A peak source/sink current, swinging rail-to-rail between GND and VDD. |
| 8 | ENB | input | Channel B enable input: when pulled low OUTB is forced low, while high or floating it lets OUTB follow INB; TTL/CMOS compatible with a 24 V maximum input tolerance and a weak internal pull-up. |
