# Hi7010

**Hichips(智芯)** · LED Drivers · SOT-23-6

Hi7010 from Hichips(智芯), in a SOT-23-6. 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 | CS | input | Current-sense input that compares the voltage across the external sense resistor with the internal 200 mV reference (overcurrent threshold 216-264 mV) to set the average LED current. |
| 2 | GND | power_in | Ground reference for the device and for the VDD bypass capacitor, which should connect to the CS sense-resistor ground at a single point. |
| 3 | VDD | power_in | Chip supply pin, clamped to about 5.0 V internally, with an absolute maximum rating of -0.3 to 7.0 V and a bypass capacitor of at least 1 µF required close to the pin. |
| 4 | NC | unconnected | No internal connection; leave this pin unconnected. |
| 5 | PWM | input | PWM dimming input where a high level enables the output and a low level turns it off, with thresholds of 1.4 V rising and 0.8 V falling, a minimum detectable pulse of 60 ns, and a floating pin defaulting to high. |
| 6 | GATE | output | Gate drive output for the external NMOS power switch. |
