A3938 - Three-Phase Power MOSFET Controller

A3938 Description

A3938 Three-Phase Power MOSFET Controller .
The A3938 is a three-phase, brushless DC motor controller.

A3938 Features

* ▪ Drives a wide range of N-channel MOSFETs ▪ Low-side synchronous rectification ▪ Power MOSFET protection ▪ Adjustable dead time for cross-conduction protection ▪ Selectable coast or dynamic brake on power-down or RESET input ▪ Fast/slow current decay modes ▪ Internal PWM current control ▪ Motor lea

A3938 Applications

* VBB must be shorted to VREG. For this condition, the absolute maximum rating of 15 V on VREG must be maintained to prevent damage to the A3938. 3 Allegro MicroSystems 955 Perimeter Road Manchester, NH 03103-3353 U. S.
