Dual 3 Phase bridge driver for brushless 3 phase motors
Features (see all):
* Available in low voltage 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 5A 50 VDC per axis
* Each 3 Phase bridge on the 7I39 has selectable overcurrent limits of .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
* Low on resistance MOSFETs and high performance gate drivers give the 7I39 high efficiency and low dead time to support high switching rates
* Gate power is derived from logic side power so that unlike other bridges, the drivers are functional all the way down to 0 V motor power supply, allowing safe and easy initial setup and testing
* Encoder and Hall effect inputs are RC filtered and processed through a Schmitt trigger before being forwarded to the controller
