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. |
