The Sanyo LB1836M is a great low-voltage dual motor driver (dual H-bridge) that we use in our micro dual serial motor controller and original Orangutan robot controllers. The low-voltage operation and relatively high peak current of 1 A make it an attractive option for those wanting to build small motion control systems powered by one or two Li-based cells or a few NiMH cells.
This TI SN754410 motor driver features two H-bridges that can be used for bidirectional control of two DC motors or to control a single stepper motor. It operates from 4.5 to 36 V and can deliver a peak current of 1 A per channel (the continuous current you can deliver depends on how well you can keep the driver IC cool).
The VNH3SP30 is a great H-bridge motor driver for motors running from 6-16 V and drawing up to about 15 A. The chip is able to withstand 40-V transients, has a peak current of 30 A, and features various fault protection features such as over-temperature and over-current shutdown. For a higher-output version, see the VN2HSP30.
The VNH2SP30 is an improved version of the VNH3SP30 motor driver, featuring current sensing, increased drive capability, and a higher maximum PWM frequency of 20 kHz.
