Hi7023

Hichips(智芯) · IC · SOP-8

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.
