Title:
CURRENT SELECTION CIRCUIT AND DRIVE CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2019/011193
Kind Code:
A1
Abstract:
A current selection circuit (102) and a drive circuit (300); the current selection circuit (102) selects an output current setting according to a resistance value of a preset current selection resistor (101), the current selection circuit (102) has an input end and an output end, the input end is connected to the current selection resistor (101), the output end is connected to a power converter (200), the current selection circuit (102) causes a resistor corresponding to the output current setting and having a predetermined resistance value to be connected to the power converter (200) via the output end, according to the resistance value of the current selection resistor (101), and the power converter (200) outputs a current according to the resistor selected by the current selection circuit (102). Current selection can be carried out flexibly, and the number of input ports of a current selection apparatus will not increase as the number of output current settings increases.
