SLM6335 from SOLA IC, in a DFN3x3-10. 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 | VIN | power_in | Input supply pin, rated to 28V absolute maximum, with a charging operating voltage of 4.35V to 6.0V. |
| 2 | VGC | passive | Internal driver gate-voltage clamp that requires a 0.1uF capacitor between VGC and VIN, with the datasheet absolute range VIN-7V to VIN+0.3V. |
| 3 | NCHRG | output | Open-drain charge-status output that is pulled low while charging and is high-impedance otherwise, rated to 28V and able to drive a red LED directly from VIN through a current-limiting resistor. |
| 4 | NSTDBY | output | Open-drain charge-complete output that is pulled low when charging is finished and is high-impedance otherwise, rated to 28V. |
| 5 | NCE | input | Enable control where a low level gives normal operation and a high level disables charging, and it can be driven by TTL or CMOS levels. |
| 6 | NTC | input | Battery temperature sense input connected to the battery NTC thermistor, where charging pauses if the pin is below 180mV or above 1.35V and leaving it floating disables temperature monitoring. |
| 7 | BAT | input | Battery voltage sense pin whose leakage current is below 3uA when charging is stopped. |
| 8 | VS | power_in | Battery current sense pin that connects to BAT through a high-precision milliohm sense resistor RS, which sets the fast-charge current as IBAT = 0.0667/RS (A). |
| 9 | GND | power_in | Power ground that must be reliably connected to the bottom thermal pad and to the PCB copper pour. |
| 10 | LX | output | Connection to the internal power MOSFET that supplies the charge current to the external inductor, rated to 14V absolute maximum. |
| 11 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
