CN5820 from ShangHai Consonance 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 | CSN | input | Negative current-sense input; the sense resistor RCS is connected between VIN and CSN, and in normal operation the average (VIN−CSN) is regulated to 160 mV. |
| 2 | DIM | input | LED brightness control input: below 0.4 V the DRV output is low (LED off), above 1.2 V it runs normal PWM with average LED current 0.16 V/RCS, and between 0.4 V and 1.2 V it gives analog dimming with average current 0.133×VDIM/RCS; PWM frequency up to 20 kHz. |
| 3 | VIN | power_in | Positive power input that supplies the internal circuitry and is the positive sense input for LED current; operating input range is 4 V to 28 V, with absolute maximum −0.3 V to 32 V to GND. |
| 4 | VCC | power_out | 5 V regulated output that requires a 4.7 µF or 10 µF filter capacitor to GND and can supply a maximum of 5 mA. |
| 5 | DRV | output | Gate drive output for the external N-channel MOSFET, with absolute maximum range −0.3 V to VCC. |
| 6 | GND | power_in | Power ground, which should be returned to system ground separately from high-current paths and the VCC capacitor ground. |
