Ⅳ、Detailed explanation of technical parameters

1. Operating voltage range

    The ChipSourceTek-CST6115 is capable of stable operation in the voltage range of 2.5V to 11V. This wide voltage range means that it can be adapted to many different types of power supplies, including battery power and power conversion directly from the grid. In battery-powered applications, such as wireless electronics and portable robots, lower operating voltages help extend battery life and improve efficiency; In applications that require higher driving forces, such as certain industrial automation equipment or large toys, a higher voltage upper limit can ensure that the motor receives sufficient power output. In addition, it also provides a low voltage detection function (VM undervoltage lock), when the power supply voltage is below a set threshold, the driver will automatically enter a protection state to prevent motor performance degradation or damage due to insufficient voltage.

2. Driving ability

    The driver has excellent current output capability. It has A rated continuous current of 1.5A and a peak current of up to 3.5A. This powerful current drive capability makes it easy to handle a variety of load conditions, from small appliances with light loads to heavy industrial equipment. For example, when driving A small fan or low-power pump, a continuous current of 1.5A is sufficient to provide the required power; In situations where instantaneous high-power output is required, such as starting a large motor or overcoming sudden resistance, the 3.5A peak current ensures the normal operation of the equipment without being affected. At the same time, the lower on-resistance (high side + low side only 320mΩ) helps to reduce power consumption and improve efficiency, allowing electrical energy to be converted into mechanical energy more efficiently.

3. Control interface

    The ChipSourceTek-CST6115 uses a simple PWM (pulse width modulation) interface to connect and control the controller. This approach has several advantages. First of all, PWM control precision is high, by adjusting the pulse width can accurately control the speed and torque of the motor, to meet the fine requirements of different application scenarios for motor control. Second, the frequency of the PWM signal can be adjusted according to specific needs to optimize the motor's response speed and running smoothness. Moreover, compared with other complex control methods, the PWM interface is simple and easy to use, requiring few external components to achieve efficient motor control circuit design, reducing the complexity and cost of the overall system. Whether using a microcontroller or a dedicated motor driver chip to generate PWM signals, it is easy to interface with the ChipSourceTek-CST6115.

4. Protective characteristic

    To ensure the safety and reliability of the system under abnormal conditions, the ChipSourceTek-CST6115 integrates a series of important protection features. These include:

•     Overcurrent protection（OCP）：When overcurrent occurs during the operation of the motor, the driver will quickly detect the abnormal current rise and automatically limit the output current to prevent the motor from being damaged due to overcurrent. This is particularly important when the motor starts at the moment or encounters sudden resistance resulting in a sharp increase in current.

•     Undervoltage shutdown（UVLO）：If the supply voltage falls below a set safety threshold (e.g. 2.5V), the driver performs an undervoltage protection action and automatically cuts off the power to the motor. This can effectively avoid motor performance degradation, control instability and possible damage to the drive itself caused by too low voltage.

•     Thermal shutoff（TSD）：When the internal temperature of the drive exceeds the safe operating range, the thermal shutdown function will be triggered to immediately stop the operation of the motor. This helps prevent the drive from burning out due to overheating, while protecting other electronic components connected to it from high temperatures. The drive can also automatically resume normal operation once the temperature returns to below normal levels.

    The presence of these protection features greatly improves the robustness and stability of the entire system, reducing the risk of equipment downtime or damage due to unexpected circumstances.

5. Low power sleep mode

    The ChipSourceTek-CST6115 also provides a practical low-power sleep mode. When the system does not need to drive the motor, the sleep mode can be activated by setting a specific input pin to low and holding it for a period of time. In sleep mode, the power consumption of the drive is greatly reduced to almost negligible. This is very valuable for portable devices that rely on battery power, as it can significantly extend the life of the battery. For example, in the electronic lock standby state, or when the toy is not in use, you can put the drive into sleep mode to save power. When the motor needs to be used again, simply change the state of the input pin to wake up the drive and return to normal operation.
