Datasheets & Reference Design

  • Refrigerator Damper and Fan Motor Control Solutions

    TIDA-00297: Refrigerators often use a damper to control airflow and a fan to provide circulation. While discrete solutions have been used for years, this TI Design uses integrated motor drivers that provide easy control, high performance, and full protection. The DRV8848 drives the stepper motor damper, and the DRV10983 drives the BLDC fan with quiet 180° commutation. The BLDC even has closed-loop speed control, using an MSP430G2553 and the DRV8812 for a PWM-based power supply. The whole solution uses a single-layer PCB. BLDC and stepper control example code is provided in the MCU firmware. Protection from over-current, over-temperature, and under-voltage are all integrated in the DRV devices.

  • LED Display Driver with Serial Interface Reference Design - TIDA-00206 - TI Tool Folder

    TIDA-00206?SYS-null-null-findchips-refdes-rd-null-wwe: This reference design drives 8 seven-segment digits with brightness control, using a low-cost MSP430 and two DRV8860 octal low-side drivers. The display module gain benefits from DRV8860 on wide supply range, high current capability, PWM brightness control, serial daisy chain connection and expandable outputs for hundreds of LEDs. A complete solution and six demo display patterns are provide with the on-board MCU program along with the integrated protection from short-circuit, under voltage, and over-temperature.

  • Low Voltage Brushed Motor System - TIDA-00115 - TI Tool Folder

    TIDA-00115?SYS-null-null-findchips-refdes-rd-null-wwe: This brushed motor system implements an MSP430 microcontroller, a DRV8837 brushed DC motor driver, and a 12V brushed motor. It is suitable for applications requiring up to 10300 RPM under no load condition. The system is 19 x 33 mm, excluding the motor, making it ideal for applications that require a small footprint. Motor power supply voltage support is 1.8V to 11V, and max current is 1.8A. Several configuration options allow for easy control over the speed of the motor's rotation, changing the direction of rotation, and sending the system into a low power state when not in operation to reduce power consumption. The motor drive stage has integrated protection from short-circuit, shoot-through, under-voltage, and over-temperature.

  • Contactless AC-Current Sensing Using a Hall Effect Sensor

    TIDA-00218: This TI Design uses Texas Instruments' Hall sensing technology to provide a solution for knowing how much AC current is flowing through a wire without any physical intervention. TIDA-00218 implements a flux concentrator to concentrate the flux around the AC current-carrying wire, rather than letting it escape in air, and then directing that flux to a hall sensor.

  • Dual High Resolution Micro-stepping Driver Reference Design - TIDA-00641 - TI Tool Folder

    TIDA-00641?SYS-null-null-findchips-refdes-rd-null-wwe: This reference design achieves a dual channel high resolution micro-stepping driver module using PWM current regulation method. Selectable micro-stepping level and current level is provided with the on-board switches. The PWM regulation scheme gives smooth phase current and ultra-low acoustic operation noise. Protections such as over current, over temperature, and short outputs are all provided along with the DRV8848 device.
