3 Description
The CSD88584Q5DC 40-V power block is an
optimized design for high-current motor control
applications, such as handheld, cordless garden and
power tools. This device utilizes TI's patented stacked
die technology in order to minimize parasitic
inductances while offering a complete half bridge in a
space saving thermally enhanced DualCool™ 5-mm
× 6-mm package. With an exposed metal top, this
power block device allows for simple heat sink
application to draw heat out through the top of the
package and away from the PCB, for superior
thermal performance at the higher currents
demanded by many motor control applications.
