ChipSourceTek-LTK8315 Product introduction

I、start

    In today's fast-paced life, the application of small electric equipment is more and more extensive. From everyday appliances to all kinds of smart devices, the performance of brushed DC motor drivers directly affects the operating efficiency and service life of these devices. Have you ever encountered problems such as unstable operation of small appliances, insufficient power of toys, and slow response of electronic locks? Today, we introduce an efficient and stable brush DC motor driver - ChipSourceTek-LTK8315, which will solve the above problems for you and bring a better experience.

II、Main body

（2.1）Functional characteristics

1. Precise control

    The ChipSourceTek-LTK8315 has two logic inputs to control the H-bridge drive. The driver consists of four n-channel metal-oxide-semiconductor field-effect tubes (MOSFETs) that are capable of bidirectional control of the motor at peak currents up to 3.5A. Whether it is starting or running, the current of the motor can be accurately adjusted to ensure the stable operation of the motor. For example, in small power tools, the output power of the motor can be accurately controlled according to different working requirements, making the operation of the tool more convenient.

2. Flexible speed regulation

    Using the current attenuation mode, the motor speed can be controlled by pulse width modulation (PWM). This speed regulation method can not only meet the requirements of the motor speed in different scenarios, but also effectively improve the energy efficiency of the motor. For example, in the field of robotics, the motor speed can be adjusted in real time according to the motion state of the robot to achieve more flexible and smooth movement.

3. Multifunction integration

    Integrated brush motor forward, reverse, stop, brake four functions, but also can drive a winding of the stepper motor. In combination with another LTK8315 alternating drive, the step function can be achieved. This means that in complex electromechanical equipment systems, it can meet a variety of different motion control needs, reducing the complexity of system design. For example, in an automated production line, a single device can achieve precise control of many different process steps.

4. Improvement of protection mechanism

    The device integrates various protection functions, such as undervoltage lock (VM undervoltage lock) and overheat protection (thermal shutdown TSD). When there is a failure, it can quickly realize the internal shutdown function, and effectively protect the safety of the motor and other related equipment. In electronic devices that run for a long time, such as large server cooling fans, the overheat protection function can avoid damage to the equipment due to motor overheating and extend the service life of the equipment.

5. Low power design

    If both inputs are set to low and held for a period of time, the motor driver will enter low-power sleep mode. This low-power design has significant advantages in some application scenarios that require high energy consumption, such as small fans in portable electronic products, electric toothbrushes, etc. When the device is in standby or does not need the motor to run, entering sleep mode can greatly reduce the overall energy consumption and extend the battery life.

6. Packaging and process environmental protection

    ChipSourceTek-LTK8315 package with bare pad back, ESOP8 package, the process is lead-free products, comply with environmental standards. This not only helps to reduce environmental pollution, but also facilitates the welding and assembly of products, and improves production efficiency.

（2.2）Scope of application

1. Small household appliance field

    In all kinds of small appliances, such as soybean milk machines, juicers, etc., LTK8315 can provide a stable and reliable drive for the motor, ensuring that the small appliances can operate normally under different working conditions. Its precise speed regulation function can adjust the motor speed according to different ingredients and processing requirements, so that food processing is more delicate and uniform. At the same time, the perfect protection function can also ensure the safety of small household appliances and extend the service life.

2. Toy industry

    For electric toys, the ChipSourceTek-LTK8315's peak current and flexible speed regulation characteristics make the toy more powerful and vivid. Whether it is the speed control of a remote control car, or the joint movement of a humanoid doll, it can achieve precise control. And the low-power sleep mode also meets the toy's battery life requirements, so that children do not need to frequently change the battery during play.

3. Electronic lock application

    In electronic locks, the reliability and stability of the ChipSourceTek-LTK8315 is Paramount. It can accurately control the rotation of the lock core motor to achieve fast unlocking and closing functions. At the same time, its protection function can prevent electronic lock failure caused by abnormal voltage or overheating, etc., to ensure family safety.

4. Robotics field

    As one of the core components of the robot, ChipSourceTek-LTK8315 can provide driving support for the robot's joint motor, mobile motor, etc. Its multi-function integration and precise control characteristics can meet the complex movement needs of the robot, making the robot's action more flexible and accurate. For example, the precise operation of industrial robots on the assembly line, and the flexible movement of service robots in various scenarios.

5. Other small power tools and mechanical and electrical equipment

    In small power tools such as small engraving machines and micro-drills, the ChipSourceTek-LTK8315 provides enough power and precise control to help users complete a variety of fine machining tasks. In mechanical and electrical equipment, such as small ventilation equipment, conveying equipment, etc., it can also ensure its stable operation.
