ChipSourceTek-CST6118 Overview and features

    The ChipSourceTek-CST6118 is a single-channel brushed DC motor drive chip designed for a variety of applications. It has many functions and excellent performance parameters, so that it can be widely used in many fields. Here is a detailed overview of the chip and its features.

The key features of ChipSourceTek-CST6118 include:

1.     Full bridge power driving structure：Built-in power MOS full bridge drive, can achieve forward, backward, stop and brake functions. This feature makes it excellent in application scenarios that require precise control.

2.     Wide operating voltage range：The operating voltage range is 1.5V to 7.2V, which allows the chip to operate stably under different voltage conditions and adapt to a variety of power supply environments.

3.     High output current：The maximum continuous output current can reach 1.8A, and the peak current can reach 2.5A, which can drive a high-power motor.

4.     Low power consumption：The circuit consumes very little static power (less than 1uA), which helps to extend battery life.

5.     Low on-resistance：The on-resistance is only 0.4Ω/1000mA, which improves energy efficiency and reduces energy loss.

6.     Built-in overtemperature protection：Built-in thermal protection (TSD) with hysteresis effect ensures safe operation of the chip under high temperature conditions.

7.     Save peripheral circuit：Full bridge drive architecture can save peripheral filter circuit, reduce cost and simplify circuit design.

8. Multiple packaging forms：Available in SOP8 package for easy integration into different board designs.

    A typical application circuit diagram of the ChipSourceTek-CST6118 shows how the chip is connected to external components to achieve its functions. For example, the C4/104P capacitor in the figure is in parallel with the motor, rather than directly mounted on the PCB. If the motor does not parallel the capacitor, a place can be reserved on the PCB for future addition. In addition, the C1, C2, and C3 capacitors in the figure can be omitted in some cases compared to similar product applications on the market, further reducing the number and cost of peripherals.

ChipSourceTek-CST6118 has a wide range of applications, including but not limited to:

•     Toy DC brush motor drive
      Electric toothbrush
      Electronic lock
      Toy motor drive
      Car mount
      Remote control car
      Adult sex toys
      Other equipment requiring precise control of motor speed and direction
