Dual H Bridge Driver handles two inductive loads.

Press Release Summary:

Designed for 2 brush type motors or other inductive loads, 7I40 is available in low-voltage and high-voltage models respectively rated at 10 A, 40 Vdc and 7 A, 80 Vdc per axis. Each bridge has selectable overcurrent limits of .75x and 1.5x rated current. Overvoltage clamp protects against inductive voltage surges, while low on resistance MOSFETs and gate drivers give 7I40 efficiency and lack of dead time needed to support switching rates to 100 kHz.

Original Press Release:

7I40 Dual HBridge

The 7I40 is a Dual H bridge driver for two brush type motors or other inductive loads. The 7I40 is available in low voltage and high voltage models(7I40L and 7I40H). The 7I40L is rated at 10A 40 VDC per axis while the 7I40H is rated at 7A 80 VDC per axis. Each bridge on the 7I40 has selectable overcurrent limits of .75 times and 1.5 times rated current. An overvoltage clamp protects the 7I40 from inductive voltage surges, reducing the need for large motor supply capacitors. Low on resistance MOSFETs and high performance gate drivers give the 7I40 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 7I40 also includes encoder input conditioning. Encoder inputs can be either single ended or differential. The 7I40 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 7I40L or 7I40H are $98 in 100s
