Abstract

The invention discloses a high-current drive circuit, including an FPGA processor, a wireless communication module, a multiplexer, a first high-current driver, a second high-current driver, a third high-current driver, a voltage stabilizing module, a power interface and Output Interface. The high-current driving circuit adopts the three-way PWM output terminals of the FPGA processor to be respectively connected to the enabling terminals of the first high-current driver, the second high-current driver, and the third high-current driver, thereby realizing the control of three different output currents. It meets the needs of electrical equipment with different power, and only controls the enable end, the control system is simple, and the failure rate of the circuit is effectively reduced.

Description

technical field [0001] The invention relates to a control circuit, especially a current driving circuit. Background technique [0002] At present, there are various high-current driving circuits. For example, in circuits for driving LEDs, especially in some high-brightness and high-power lighting occasions, LEDs are not widely used. The main reason is that the driving power of traditional high-power LED lamps is poorly controllable, which greatly reduces the convenience of use. So it is necessary to design a controllable high current drive circuit. Contents of the invention [0003] Purpose of the invention: to provide a controllable high-current drive circuit, thereby improving the convenience of using the drive circuit. [0004] Technical solution: The high-current driving circuit described in the present invention includes an FPGA processor, a wireless communication module, a multiplexer, a first high-current driver, a second high-current driver, a third high-current ...
