| 发明名称 | Programmable light emitting diode (LED) driver technique based upon an input voltage signal | ||
| 摘要 | Provided is an LED driver including an amplifier configured to receive a negative voltage input signal and produce a positive voltage output signal in response thereto. Also included is a microcontroller configured for sensing a value of the positive voltage output signal. The microcontroller (i) enters a programming mode when the value exceeds a threshold and (ii) produces an output current responsive to the value. | ||

| 主权项 | 1. A light emitting diode (LED) driver, comprising: an amplifier configured to receive a negative voltage input signal and produce a positive voltage output signal in response thereto, wherein the negative voltage input signal is representative of programming data; a microcontroller configured to sense a value of the positive voltage output signal; wherein the microcontroller (i) enters a programming mode when the value exceeds a threshold and (ii) produces an output current responsive to the value. | ||
