Bridge driver handles low, high voltages

The 7I39 dual three-phase bridge driver for brushless three-phase motors is available in low- and high-voltage models. The low-voltage model is rated at 10 A 25 Vdc per axis, while the high-voltage model is rated at 5 A 50 Vdc per axis.

Each three-phase bridge on the 7I39 has selectable overcurrent limits of 0.75 times and 1.5 times rated current. An overvoltage clamp protects the 7I39 from inductive voltage surges, reducing the need for large motor supply capacitors. ($98 ea/100—available now.)
