CN5502 from ShangHai Consonance Elec, in a SOP-8-EP. 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 | EQ | passive | LED current-balancing pin: tie the EQ pins of all CN5502 devices together when several drive parallel LED strings, otherwise leave it floating. |
| 2 | EN | input | High-voltage enable input: a logic high (VIH min 3.1 V) runs the device and a logic low (VIL max 0.6 V) disables it. |
| 3 | GND | power_in | Ground, the negative terminal of the input power supply. |
| 4 | CS | input | LED current sense pin: the LED current is set by the resistor RCS between CS and GND using ILED = 0.153 ÷ (RCS + 0.03), with CS voltage 144 to 160 mV in normal operation. |
| 5 | LED | output | LED current input pin connected to the internal MOS drain, with the LED string between VIN and this pin; absolute maximum voltage is 36 V. |
| 6 | VIN | power_in | Positive input supply pin that powers the internal circuits; operating input range is 4 V to 32 V. |
| 7 | VCC | power_out | +5 V regulated output (5 V typical, 3 mA maximum) when VIN is above 5.5 V, requiring a 2.2 uF to 10 uF capacitor to GND. |
| 8 | DIM | input | LED brightness control input accepting analog or PWM signals; external PWM is 80 Hz to 400 Hz, with low below 0.3 V and high above 1.25 V. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
