6.1 Application Information

Historically, battery powered tools have favored brushed DC configurations to spin their primary motors, but more recently, the advantages offered by brushless DC operation (BLDC) operation have brought about the advent of popular designs that favor the latter. Those advantages include, but are not limited to higher efficiency and therefore longer battery life, superior reliability, greater peak torque capability, and smooth operation over a wider range of speeds. However, BLDC designs put increased demand for higher power density and current handling capabilities on the power stage responsible for driving the motor.

The CSD88599Q5DC is part of TI’s power block product family and is a highly optimized product designed explicitly for the purpose driving higher current DC motors in power and gardening tools. It incorporates TI’s latest generation silicon which has been optimized for low resistance to minimize conduction losses and offer excellent thermal performance. The power block utilizes TI’s stacked die technology to offer one complete half bridge vertically integrated into a single 5-mm × 6-mm package with a DualCool exposed metal case. This feature allows the designer to apply a heatsink to the top of the package and pull heat away from the PCB, thus maximizing the power density while reducing the power stage footprint by up to 50%.
