CN5730 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 | MODE | input | Mode select pin: tied to GND gives off/high-power/flash cycling, floating gives off/high-power/low-power cycling, and tied to VCC gives a four-state off/high/low/flash cycle, all advanced by BTN presses. |
| 2 | ISET | passive | Sets the full-power LED current through a resistor RISET to GND using I_LED = 1800 V / RISET (I_LED in A, RISET in Ω), for example 1.8 kΩ gives 1 A. |
| 3 | GND | power_in | Power ground for the device and the LED return path. |
| 4 | VCC | power_in | Supply input that must stay between 2.85 V and 6 V and must exceed the LED forward voltage plus the VCC-to-LED pin drop for proper operation. |
| 5 | LED | output | LED current sink output: the LED anode connects here with the cathode to GND, and the LED current flows out of this pin with a maximum of 1.5 A. |
| 6 | CT | passive | Timing capacitor pin that sets the flash-state blink period from the capacitance C on this pin; connect CT to VCC if the flash function is not used. |
| 7 | BTN | input | Pushbutton input that is connected to GND through the switch, with an internal pull-up of about 52 kΩ and built-in debounce of 20 to 52 ms (36 ms typical), and each valid press changes the LED state. |
| 8 | CE | input | Chip enable input where a high level (VCEH minimum 2.3 V) enables normal operation and a low level (VCEL maximum 0.6 V) disables the chip, and it accepts TTL or CMOS levels. |
| 9 | EP | power_in | Exposed thermal pad on the package underside that is ground and must be soldered to the PCB ground copper for maximum heat dissipation and LED current. |
