The LB1696-E is an integrated circuit that is becoming increasingly important in the power management and motor control industry. It has a variety of applications such as controlling the speed of motors and eliminating electric noises from automotive systems. The LB1696-E is an advanced integrated circuit that combines the best of both analog and digital technologies, allowing for greater flexibility and better integration into systems.

Overview of the LB1696-E

The LB1696-E is an analog motor control circuit that can operate from a single voltage supply. It can handle both high and low voltage motor applications, up to 16V, and incorporates temperature compensation and current-limit protection to ensure reliable motor performance. It also features a built-in current-modulation scheme, allowing for precise control over a range of motor currents.

The LB1696-E utilizes an advanced digital-to-analog conversion (DAC) to provide high accuracy and resolution in controlling motor speed. It also features a high-speed true-RMS thermally compensated current-mode control architecture. This means the LB1696-E is capable of controlling motors in either open- or closed-loop settings.

Features of the LB1696-E

The LB1696-E has many useful features, allowing for precise control over motors. It has a quiescent current as low as 250μA and includes a bi-directional stealth mode for reversible motion. It also offers programmable current regulation and smooth starting and stopping for improved motor control accuracy. Furthermore, the LB1696-E provides pulse-by-pulse current limitation, allowing for precise current control even when the motor is running at high speeds.

The LB1696-E also offers an integrated driver circuitry, which eliminates the need for an external transistor. Its low-noise pulse-width modulated (PWM) output makes it suitable for driving a stepper motor with minimal electrical noise. Additionally, the LB1696-E includes a low standby-mode current consumption for improved power-management efficiency.

Applications of the LB1696-E

The LB1696-E is suitable for a wide range of applications, from precision stepper control to light dimming and motor speed control. It is ideal for robotics applications and can be used in conjunction with an encoder or a rotary potentiometer to provide precise angular control without the need for an external motor drive. Furthermore, it can be used in medical equipment to control the speed and torque of a motor, and its low-noise characteristics make it well-suited for audio applications.

The LB1696-E also finds application in industrial automation, where it can be used to precisely control stepper and brushed motors. It can be used in automated systems to provide precise control of motor speed, torque, and direction. Furthermore, its low power consumption makes it suitable for battery-powered applications.

Working Principle of the LB1696-E

The LB1696-E works on the principle of pulse-width modulation (PWM). This technique is used to control the speed of a motor by varying the width of the pulses sent to the motor. The width of the pulse is determined by the voltage applied to the motor. As the voltage increases, the pulses become longer and the speed of the motor increases. Conversely, when the voltage decreases, the pulses become shorter and the motor speed decreases.

The LB1696-E also uses a current-modulation scheme. This technique uses a duty cycle to determine the amount of current sent to the motor. The duty cycle is a value between 0 and 1 that describes the proportion of time that a certain amount of current is applied to the motor. The higher the duty cycle, the more current will be sent to the motor.

The LB1696-E also features a built-in thermal compensation system. This system monitors the temperature of the motor and adjusts the pulse width of the PWM signal accordingly. This ensures that the motor is always running at optimum efficiency and helps prevent any damage caused by excessive heat.

Conclusion

The LB1696-E is a powerful integrated circuit that can be used to precisely control the speed, current, and direction of motors in a variety of applications. Its integrated driver circuitry and advanced digital-to-analog conversion make it suitable for precision control of stepper and brushed motors. Additionally, its low standby-mode current consumption and high-speed true-RMS thermally compensated current-mode control make it well-suited for battery applications.
