PI-IPM System Block Schematic:
Description
The PIIPM50P12B004 is a fully integrated Intelligent Power
Module for high performances Servo Motor Driver applications.
The device core is
a
state of the art DSP, the
TMS320LF2406A* at 40 Mips, interfaced with a full set of
peripheral designed to handle all analog feedback and control
signals needed to correctly manage the power section of the
device.
The PI-IPM has been designed and tailored to implement
internally all functions needed to close the current loop of a
high performances servo motor driver, a basic software is
already installed in the DSP and the JTAG connector allows
the user to easily develop and download its own proprietary
algorithm.
The device comes in the EMPTM package, fully compatible in
length, width and height with the popular EconoPack 2 outline.
*Beta samples come with the TMS320LF2406 at 30Mips, please refer to TI datasheet
for further information about performances.
