This paper presents a photovoltaic control system with mixing-mode chip design. The chip includes the photo sensor, amplifier and digital decision core, and driver circuits. The photo-sensor is implemented with the p+/n− well diodes to generate the photo current with the array of diodes.
However, the photo sensor, digital control and driver are rarely integrated with a single MOS chip for lighting control. In this paper, the digital control and the analog sensor are integrated for LED streetlight-control by mixing-mode chip design. The design includes the sensing circuits, analog amplifier, digital control and power driver.
The function can meet our specification. In this paper, a photovoltaic system for LED control is designed with a single chip. The chip is successfully implemented with the integration of photosensor, operational amplifier, digital control and LED driver, for the lighting control system.
They use the internal ESD diode between the CE ( chip enable ) input and ground for charging the NiCd cell from the solar panel, but also use the voltage ( or lack thereof ) from the solar panel to detect when it is dark enough to turn the LED on. The CE input includes a small pull-up current. I measured about 30 uA with 1.25 volts on VDD .
The chip is successfully implemented with the integration of photosensor, operational amplifier, digital control and LED driver, for the lighting control system. To meet various environments, the sensitivity for photo detection can be adjusted with I/O control by users. The chip only employs about 500 of MOS and diodes.
Figure 1 shows the LED lighting control system consisting of solar cell and photovoltaic sensor [ 12, 13 ]. The battery can be charged by the solar plane in the day, and it is discharged to LED lighting in the night. The photo-sensor is used to control LED on or off in the night or day automatically.
