Power management integrated circuits (PMICs) are found in almost all electronic devices, from consumer and medical equipment to industrial applications. They are necessary for delivering the highest performance, reliability, and energy efficiency to small electronics such as smartphones and tablets. The TB6586FG, C8, EL, and HZ are examples of PMICs that are used to control and power motors, controls, and even communications, depending on the application.

Types of PMICs

A PMIC is any integrated circuit (IC) that provides power and related functions for electronic devices. They can be broken down into a few categories depending on their function. These categories include power regulation, motor control, LCD display drivers, and wireless communication, among others.

TB6586FG, C8, EL, and HZ – Motor Drivers, Controllers, and More

The TB6586FG, C8, EL, and HZ PMICs are motor drivers and controllers that are designed to power and control small motors in applications such as electric vehicles, drones, and other robotic systems. They are also suitable for several other applications, including LED lighting, brushless DC motor (BLDC) drives, electromechanical actuators, and communications systems.

TB6586FG

The TB6586FG is a high-efficiency, 3-channel motor driver with a voltage range of 2.5 V to 24 V and a current range of up to 4 A per channel. It includes an integrated buck-boost converter to boost the power supply voltage and provide a stable output current. The TB6586FG also features a low on-resistance (0.45 Ω) and low power dissipation, enabling higher energy efficiency and superior motor control performance. Furthermore, the integrated bootstrap controller simplifies the motor drive circuit, reducing the external components and cost.

C8

The C8 is a 5-channel, high-performance motor driver/controller. It has a voltage range of 2.5 V to 32 V and a current range of up to 5 A per channel. The C8 features a low on-resistance (0.35 Ω) to ensure reliable control and efficient operation. It also includes a high-frequency PWM circuit and a low-noise filter network, both of which are designed to provide smooth, efficient motor control.

EL

The EL is a 3-channel, low-noise motor driver/controller with a voltage range of 2.5 V to 28 V and a current range of up to 4 A per channel. It also has a low on-resistance (0.4 Ω) for efficient operation. The EL is designed for applications that require low noise and low motor speed ripple, making it ideal for applications such as respirators, medical pumps, and industrial automation systems.

HZ

The HZ is a 4-channel, high-performance motor driver with a voltage range of 2 V to 36 V and a current range of up to 10 A per channel. It has an integrated buck-boost converter and a low on-resistance (0.35 Ω) for efficient operation and superior motor control performance. The HZ is suitable for applications requiring high-power outputs, such as industrial drives, drones, and robotics.

Working Principle

PMICs provide power and related functions to electronic devices. They are typically used to convert AC or DC power from a power supply into different voltages and currents needed by the device. They also provide over-voltage, over-current, and short-circuit protection to ensure the device’s stability, reliability, and longevity.

How a motor driver/controller works depends on the design of the IC. Generally, it involves the following steps:

• Voltage-to-current conversion: The voltage supplied to the motor is converted to a current. This is done using a control circuit that is typically an integrated Pulse Width Modulation (PWM) circuit or a switching amplifier.
• Control logic: The current is then controlled using a logic circuit, which is responsible for providing a reference for the current and checking for errors.
• Power switch: The last stage is the power switch, which is responsible for controlling the supply voltage to the motor. Depending on the type of PMIC, this switch may be an insulated gate bipolar transistor (IGBT), field effect transistor (FET), or other switch type.

By controlling the voltage and current supplied to the motor, a PMIC can precisely control the speed, position, and direction of the motor’s rotation. This functionality makes motor driver/controllers such as the TB6586FG, C8, EL, and HZ highly useful for applications requiring precise motor control.

Conclusion

PMICs are an essential component of almost all electronic devices. The TB6586FG, C8, EL, and HZ PMICs are motor drivers/controllers used in applications such as electric vehicles, drones, LED lighting, and brushless DC motor drives. They are able to precisely control the voltage and current supplied to the motor, enabling precise motor control. PMICs are not only necessary for devices to operate efficiently and reliably, but also for providing users with the best possible experience.
