Hi7023 from Hichips(智芯), in a SOP-8. 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 | NC | unconnected | No internal connection is specified for this pin (listed as "----" in the pin function table). |
| 2 | PWM | input | PWM dimming input: the chip operates when PWM is high and the output is off when low, with detection thresholds of 1.4 V (rising) and 0.8 V (falling), a 60 ns minimum pulse response, and an absolute maximum range of -0.3 to 7.0 V; it defaults to high when left floating. |
| 3 | VIN | power_in | Supply input with a start-up threshold of 4.7 V and a shut-off threshold of 3.8 V; the datasheet recommends a minimum operating voltage of 6.5 V, a bypass capacitor of 1 uF or more placed close to the pin, and an absolute maximum of -0.3 to 80 V. |
| 4 | CS | input | Current-sense input connected to the source of the internal power MOSFET, where the 251 mV reference sets the average LED current via the sense resistor, with an absolute maximum range of -0.3 to 7.0 V. |
| 5 | D | output | Drain of the internal power MOSFET, rated -0.3 to 60 V for the Hi7023 (100 V for Hi7023H), and this pin is a heat-sink pin that must be thermally managed. |
| 6 | D | output | Drain of the internal power MOSFET, rated -0.3 to 60 V for the Hi7023 (100 V for Hi7023H), and this pin is a heat-sink pin that must be thermally managed. |
| 7 | GND | power_in | Chip ground. |
| 8 | GND | power_in | Chip ground. |
