This tiny breakout board for TI’s DRV8833 dual motor driver can deliver 1.2 A per channel continuously (2 A peak) to a pair of DC motors. With an operating voltage range from 2.7 V to 10.8 V and built-in protection against reverse-voltage, under-voltage, over-current, and over-temperature, this driver is a great solution for powering small, low-voltage motors.

 

Texas Instruments’ DRV8833 is a dual H-bridge motor driver IC that can be used for bidirectional control of two brushed DC motors at 2.7 V to 10.8 V. It can supply up to about 1.2 A per channel continuously and can tolerate peak currents up to 2 A per channel for a few seconds, making it an ideal driver for small motors that run on relatively low voltages. Since this board is a carrier for the DRV8833, we recommend careful reading of the DRV8833 datasheet (1MB pdf). The board ships populated with SMD components, including the DRV8833, and adds a FET for reverse battery protection.

This board is very similar to our DRV8835 dual motor driver carrier in operating voltage range and continuous current rating, but the DRV8835 has a lower minimum operating voltage, offers an extra control interface mode, and is 0.1″ smaller in each dimension; we also carry a DRV8835 dual motor driver shield that is easy to use with an Arduino. The DRV8833 has a higher peak current rating (2 A per channel vs 1.5 A), optional built-in current-limiting, and no need for externally supplied logic voltage.

For a smaller, lower-cost, single-channel alternative to this driver, please consider our DRV8838 carrier, which offers a similar operating voltage range and current capabilities.

For higher-voltage alternatives to this driver, consider our A4990 and DRV8801 motor driver carriers.

 

这款基于德州仪器DRV8833双电机驱动器的微型分线板,可以为每对通道连续提供1.2 A(2 A峰值)。 该驱动板具有2.7 V至10.8 V的工作电压范围,并内置防反向电压、欠压、过流和过温保护,是小型低压电机供电的理想解决方案。

概述

德州仪器的DRV8833是一款双H桥电机驱动器IC芯片,可用于双向控制2.7 V至10.8 V的两个有刷直流电机。它可以连续提供高达每通道1.2 A的电流,并且可以承受高达2 A每通道几秒钟,使其成为在相对低电压运行的小型电机的理想驱动器。由于该板是基于DRV8833的分线板,我们建议仔细阅读DRV8833数据手册(1MB pdf)。板上装有SMD元件,包括DRV8833 IC芯片,并增加了一个FET(场效应管)用于反向电池保护。
该板与我们的DRV8835双电机驱动器分线板在工作电压范围和连续电流额定值非常相似,但DRV8835具有较低的最低工作电压,提供额外的控制接口模式,每边尺寸小0.1英寸;还带一个易于与Arduino一起使用的DRV8835双电机驱动器板卡。 DRV8833具有更高的峰值电流额定值(每通道2 A 对比1.5 A),可选内置限流,无需外部提供逻辑电压。
寻求更小、更低成本的单通道替代驱动器,请考虑我们的DRV8838分线板,它提供了类似的工作电压范围和电流能力。
寻求更高电压替代驱动器,请考虑我们的A4990和DRV8801电机驱动器分线板。
