Mouser offers TI dual H-bridge motor driver
Mouser Electronics is targeting industrial motor control applications and robotics with the DRV8843 dual H-bridge driver from Texas Instruments which capable of driving two DC motors or one stepper motor.
The output block of each driver consists of n-channel power mosfets configured as H-bridges that are able to supply up to 2.5A peak or 1.75A RMS output current.
The DRV8843 integrates the LM5101B mosfet driver, the LM3S8971 Stellaris motor controller, the AMC1200 isolation amplifier and the DRV8312 motor driver.
It is available in a thermally enhanced 28-pin HTSSOP package and both single- and three-phase motors can be controlled, as well as applications with and without sensors.
There is also the DK-LM3S-DRV8312 motor control design kit for 3-phase brushless DC motors. The kit has an LM3S818 MCU on a controlCARD module that is pre-programmed with all the necessary firmware.
Also included is the Crosshairs embedded kernel and corresponding PC application interface that enables the engineer to control and monitor the system.
