The devices also provide the lowest operating voltage and standby current to reduce power consumption by up to 75 percent.
Key features and benefits of the DRV10866 and DRV11873:
•Highly integrated: Single motor driver eliminates the need for external gate drivers, inverters, position detection and feedback, along with a microcontroller and firmware, to cut board space, system cost and development time.
•Spins motors in minutes: Utilizes TI InstaSPIN-FAN motor solutions, a fully protected robust solution with no coding and very few external components needed to get motors spinning.
•Reduces power consumption by up to 75 percent: Wide operating voltage range of 1.65 V to 5.5 V and low quiescent current of 5 uA extends the battery life of portable devices, such as toothbrushes and shavers, compared to existing solutions.
•Flexibility to add advanced control: Can be combined with a TI MSP430 MCU for designs requiring user interface and closed-loop speed control.
•Robust, reliable and fully protected: Advanced on-chip protection, including over-current, over-temperature, shoot-through and under-voltage lock-out, increases system reliability.
Tools and support
In addition to the motor driver, the DRV10866EVM and DRV11873EVM evaluation modules include a simple TLC555 timer, frequency generator output, PWM input and motor connection to enable fast, code-free motor evaluation. Both EVMs ship with schematics and gerber files for a suggested retail price of US$25.
Package, availability and pricing
The DRV10866 and DRV11837 are available today in a 3-mm by 3-mm SON package for a suggested retail price of $0.39 and 16-pin TSSOP for suggested retail price of $0.89, respectively, in 1,000-unit quantities.
