SL27511 from Slkor SLKORMICRO Elec, in a SOT-23-6. 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 | VDD | power_in | Supply pin, recommended 4.5 V to 20 V with an absolute maximum of 24 V to GND; the internal UVLO forces the outputs low when VDD falls below its threshold. |
| 2 | OUTH | output | High-side gate drive output from a composite P-MOSFET plus N-MOSFET pull-up, rated for 4 A peak source current and swinging rail to rail between VDD and GND. |
| 3 | OUTL | output | Low-side gate drive output from an N-MOSFET pull-down, rated for 8 A peak sink current, with absolute limits of -0.3 V to VDD+0.3 V on the output nodes. |
| 4 | GND | power_in | Ground reference for the supply and the gate driver outputs, to which all voltage ratings are referenced. |
| 5 | IN- | input | Inverting logic input, TTL and CMOS compatible, with a recommended range of 0 V to 20 V and an absolute range of -5 V to 24 V; it is weakly pulled up so the output is driven low if it floats. |
| 6 | IN+ | input | Non-inverting logic input, TTL and CMOS compatible, with a recommended range of 0 V to 20 V and an absolute range of -5 V to 24 V; it is weakly pulled down so the output is driven low if it floats. |
