SL27523

Slkor(SLKORMICRO Elec.) · Gate Drive ICs · SOP-8

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.
