Dual 2 kW H-Bridge Driver works with 4I27 and FPGA cards.January 15, 2008 -
Designed for use with 2 brush type motors or other inductive loads, 7I29 is rated at 15 A continuous @ 175 Vdc per axis. Selectable overcurrent limits for each bridge is .75 and 1.5 times rated current. MOSFETs and gate drivers promote efficiency and minimize dead time to support switching rates to 100 KHz, while gate power is derived from logic side power so that drivers are functional down to 0 V motor power supply. Driver includes encoder input conditioning.

Dual 2KW H-Bridge for 4I27 and FPGA Cards
The 7I29 is a Dual H bridge driver for two brush type motors or other inductive loads. The 7I29 is rated at 15A continuous at175 VDC per axis. Each bridge on the 7I29 has selectable overcurrent 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 unlike other bridges, 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 is compatible with the MESA's 4I27 or the 4I34M, 4I65, 4I68, 5I20, 5I22 and 7I60 Anything I/O cards with SoftDMC or HostMot firmware, or can be used with a customer supplied controller.
Price of the 7I29 is $205 in 100's
