Hi7020
Hichips(智芯) · LED Drivers · SOT23-6
Hi7020 from Hichips(智芯), in a SOT23-6. 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 the internal error amplifier compares against the 0.251 V internal reference to regulate output current, with an absolute maximum voltage of -0.3 V to 7.0 V. |
| 2 | GND | power_in | Chip ground, which the VIN decoupling capacitor (1 uF or larger) must be connected to close to the VIN pin. |
| 3 | VIN | power_in | Supply input with an absolute maximum of -0.3 V to 80 V, where the chip starts at 4.7 V, shuts off at 3.8 V, and 6.5 V or higher is recommended for stable operation. |
| 4 | NC | unconnected | No connection; the datasheet lists this pin as having no function. |
| 5 | PWM | input | PWM dimming input with absolute maximum of -0.3 V to 7.0 V, where high enables the output and low disables it, with rising threshold 1.4 V and falling threshold 0.8 V, and it defaults high when floating. |
| 6 | GATE | output | Drives the gate of the external N-channel MOSFET; the datasheet gives no separate voltage limit for this pin. |
