Gochip is about to launch the GH42xx series of 24V single coil DC brushless motor driver chips, which adopt advanced high-voltage BCD technology and can meet various segmented applications of single coil fans, water pumps, and motors. This series integrates high-sensitivity Hall sensors and current drive modules internally, simplifying the overall PCB peripheral design and making it more suitable for manufacturing miniaturized fan and motor control board applications.

The GH42xx series chip has a built-in power reverse protection function, which protects the chip from damage when the power is reversed. It also has an overheat protection function to ensure that the motor driver will not be damaged at high temperatures.

Due to the full bridge structure adopted by the GH42xx series output driver stage, which has the characteristics of high output efficiency and low ripple, it can be applied to high demand application scenarios such as consumer electronics, industrial, small household appliances, energy storage, etc.

There are two models of motor drive chips in this series: GH4232 and GH4212. GH4232 has the characteristics of wide working voltage, strong current driving capability, and high sensitivity, which can effectively improve the efficiency and reliability of DC motors/fans.

GH4212 has been upgraded on GH4232, and its chip has built-in stall protection function, which can effectively prevent damage caused by IC overheating and long-term locked rotor conditions, extending the service life of the machine.
