PMIC— Motor Drivers, Controllers

Power Management Integrated Circuits (PMICs) are circuits that contain a number of components that can be used to regulate power delivery to different electrical components in a device. Motor Drivers, Controllers, and other related components are used to manage and distribute power from the power source to the various parts of a device.TB6585AFTGC8,EL is one of these types of ICs and it is specifically designed for automotive applications. It is a 3-phase motor driver controller IC that is capable of driving up to 6-stages of stepper or brushless DC (BLDC) motors and solenoids. This chip is ideal for use in areas such as the automotive industry, appliances, and general-purpose equipment.

The TB6585AFTGC8EL is a highly integrated device that integrates several components such as a Pre-Driver, 3-phase Driver, On-chip Diagnostics and Protection, Pulse-Width-Modulated (PWM) Generators, Fault Signal and Mute, RPM/Torque Control, and Gate/Field Drivers.

The Pre-Driver section of the device consists of two differential inputs (INx and GNDx) and two non-inverting outputs (OUTx and UVW) for driving a 3-phase BLDC motor. The Pre-Driver output is connected to the 3-phase driver circuit, which consists of three separate outputs (VREF, and GNDx are connected to the three power stage MOSFET channels). Each of the three power stages consists of a low-side gate driver and MOSFETS, and each channel is independently PWM controlled. The TB6585AFTGC8EL also includes an on-chip diagnostics and protection circuit to check the status of the power stage MOSFETs against a preset limit, as well as monitor the level of current and other characteristics. In addition, it may also detect faults in the motor and provide an appropriate fault signal.The PMW generator circuits provide the appropriate PWM signals to drive the power stages, and the RPM/torque control block provides the necessary control laws for managing the speed and torque of the motor. The Gate/Field Drivers generate the signals necessary to drive the motor, such as motor torque and slip-speed, and to control the inverter stages.The TB6585AFTGC8EL has a variety of features that make it ideal for use in automotive applications. It has a low-input voltage range of 2.4V to 6V, low-output voltage range of 0V to 3.3V, and low-consumption current of 15mA. The device is rated for a logic supply voltage of 1.8V to 5.5V, and the output current capability is up to 2A continuous and 4A peak.

In conclusion, the TB6585AFTGC8EL is an ideal choice for automotive and other general-purpose applications. With a host of features and integrated components, this IC can provide reliable power management and fault protection, as well as speed and torque control. This chip can be used to drive BLDC motors, solenoids, and other types of components with the necessary efficiency and reliability. The chip can be easily integrated into a wide variety of systems to enhance the design and provide optimal performance.
