Hi7023H

Hichips(智芯) · IC · SOP-8

Hi7023H 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; the datasheet lists this pin as NC with no function.
2 PWM input PWM dimming input: the chip operates when high and the output is off when low, with VPWM absolute maximum of -0.3 to 7.0 V, detection thresholds of 1.4 V rising and 0.8 V falling, and pulses as short as 60 ns responded to; floating defaults to high.
3 VIN power_in Supply input: the chip starts above 4.7 V and turns off below 3.8 V, with an absolute maximum of -0.3 to 80 V, a recommended minimum operating voltage of 6.5 V, and a capacitor of more than 1 uF to GND placed next to the pin.
4 CS input Source of the internal power MOSFET and current-sense input, referenced to a 251 mV control voltage with an absolute maximum of -0.3 to 7.0 V, where output current is set by Iout = 0.251 V / Rcs.
5 D output Drain of the internal power MOSFET, rated for an absolute maximum of -0.3 to 100 V on the Hi7023H, and this pin requires heat-sinking treatment as noted by the datasheet.
6 D output Drain of the internal power MOSFET (second pin of the drain pair), rated for an absolute maximum of -0.3 to 100 V on the Hi7023H, and this pin requires heat-sinking treatment as noted by the datasheet.
7 GND power_in Chip ground pin, to be connected to the system ground.
8 GND power_in Chip ground pin (second ground pin), to be connected to the system ground.
