Abstract
A monolithic bus slave circuit structure is provided, including: a monolithic integrated chip, a rectifier bridge, a first light circuit, a second light circuit, and a third light circuit. The monolithic integrated chip includes a bus voltage input pin, a ground pin, a first drive signal output pin, a second drive signal output pin, a third drive signal output pin, and a power output pin. Both the bus voltage input pin and the ground pin are connected to an output end of the rectifier bridge, two input ends of the rectifier bridge are connected to a positive line and an negative line of a bus respectively, the ground pin is grounded. The monolithic bus slave circuit structure realizes the intelligent constant current drive function and drive the light circuits with constant current in the voltage range of the whole bus, which does not depend on the parameters of the LEDs.
