Richmond, Calif.Mesa Electronics has developed the 7I29 dual H-bridge driver for two brush type motors or other inductive loads.
The 7I29 is rated at 15A continuous at 175 VDC per axis. Each bridge on the 7I29 has selectable over-current limits of .75 times and 1.5 times rated current.
Low on-resistance MOSFETs and high-performance gate drivers give the 7I29 high efficiency and low dead-time to support switching rates up to 100 KHz. Gate power is derived from logic side power so that the drivers are functional all the way down to 0V motor power supply, allowing safe and easy initial setup and testing.
The 7I29 has 2500V RMS isolation from motor power to logic side control signals. The 7I29 also includes encoder input conditioning. Encoder inputs can be either single ended or differential.
The 7I29 costs $205 in 100-piece quantities.
