ChipSourceTek-LTK8530 is a powerful and widely used brushed DC motor driver for small appliances, toys, electronic locks, advanced robots, digital products, and other small power tools and electromechanical equipment. The driver controls the H-bridge through two logical inputs and consists of four n-channel metal-oxide-semiconductor field-effect tubes (MOSFETs), capable of bidirectional control of the motor at peak currents up to 5.5A. With the current attenuation mode, the motor speed can be precisely controlled through pulse width modulation (PWM). If these two inputs are set to low and left on for a period of time, the drive will enter low-power sleep mode, further saving energy.

    The ChipSourceTek-LTK8530 integrates a variety of core functions, including forward, reverse, stop and brake of the brush motor, while also driving one of the winding of the stepper motor, which is used in conjunction with another ChipSourceTek-LTK8530 to achieve the stepper function. The device also integrates a number of protection functions to achieve internal shutdown in case of failure, providing overcurrent protection, undervoltage lock and overheat protection to ensure safe and stable operation of the device. In addition, a low-power sleep mode is provided to reduce energy consumption when not in use. The ESOP8 package with bare pads on the back of the package is lead-free and meets environmental standards.

Product function introduction

1. High efficiency motor drive

•     Single channel H-bridge motor driver with current control：The ChipSourceTek-LTK8530 uses an advanced H-bridge design to efficiently drive a single winding of a DC motor or a stepper motor. It has a high + low total resistance of only 120mΩ, ensuring low power consumption and high efficiency.

• Pulse width modulation (PWM) control interface：Through the PWM control interface, the user can flexibly adjust the speed of the motor to meet the needs of various application scenarios.

• Average current drive capacity：The ChipSourceTek-LTK8530 has an average current drive capability of 3.0A, providing sufficient power support in conventional applications.

• Peak current drive capability：Its peak current drive capability of up to 5.5A enables it to perform well under transient high loads and meet the needs of complex operating conditions.

2. Multifunction integration

• Multifunction control：Integrated brush motor forward/reverse/stop/brake four functions, simplify the peripheral circuit design, reduce the complexity of the system.

• Stepper motor drive：In addition to driving the brushed motor, the ChipSourceTek-LTK8530 can also drive a winding of the stepper motor to achieve the stepping function in conjunction with other drivers, which provides a solution for applications requiring high precision positioning.

• Low power sleep mode：When the motor is not needed to drive, both inputs can be set to low and held for a period of time, putting the drive into low-power sleep mode and significantly extending the standby time of the device.

3. Comprehensive protection mechanism

• Output overcurrent protection（OCP）：When an abnormal output current is detected, the ChipSourceTek-LTK8530 will respond quickly and automatically shut down the output to prevent device damage due to overcurrent.

• Undervoltage locking（UVLO）：When the supply voltage is lower than the set value, the driver will automatically lock and stop working to avoid unstable operation caused by insufficient voltage.

• Thermal shutoff（TSD）：In the event of overheating, the internal temperature sensor triggers the thermal shutdown function, immediately cutting off the output and protecting the driver and the driven device.

• Automatic fault recovery：After troubleshooting, the ChipSourceTek-LTK8530 automatically returns to normal operation, reducing manual intervention and maintenance costs.

4. Wide range of application scenarios

• Small household appliances：Such as air purifiers, electric shavers, etc., ChipSourceTek-LTK8530 can provide a stable and reliable power source for these devices.

• plaything：Whether it's a remote control car or an electric doll, the ChipSourceTek-LTK8530 provides precise speed control to enhance the user experience.

• Electronic lock：For the driving part of smart door locks, ChipSourceTek-LTK8530's high reliability ensures the safety and stability of electronic locks.

• Advanced robot：In the field of robotics, the ChipSourceTek-LTK8530 not only drives joint motion, but also enables complex path planning and motion control.

• Digital product：For example, portable printers, scanners, etc., ChipSourceTek-LTK8530 provides efficient driving solutions.

• Other small power tools and mechanical and electrical equipment：Such as hand-held stirrers, small fans, etc., LTK8530 can do.
