Zhongke Semiconductor announced mass production of the CT1906H motion control chip, which uses a monolithic integrated GaN HEMT process to integrate 6 GaN half-bridge power transistors and 3-channel gate drivers into a 5×5mm LGA package, targeting micro servo joints with outer diameters of 14–45mm. According to Zhongke Semiconductor, the CTUnite platform measured continuous output of 13.65A under 48V supply and a chip junction temperature of 64°C, corresponding to 655W; on a 30×30mm driver board, without an external heatsink, under sealed simulated conditions, it continuously output 392W at 48V supply and a junction temperature of 73°C. The above data come from platform measurements; the chip's actual performance still requires further verification through large-volume installation and long-term operating-condition aging tests.
