Reference designs for 2S-6S and 8S-15S power tools

STEVAL-PTOOL1V1 and STEVAL-PTOOL2V1 are two ready-to-use system solutions tailored for power and garden tools driven by 3-phase brushless motors and supplied respectively from 2S to 6S and from 8S to 15S battery packs.

Discover 2 reference designs implementing a set of functionalities and architecture solutions required by power tools.

STEVAL-PTOOL1V1 - Compact ready-to-use reference design for low voltage 2S-6S power tools

Highly compact 70 x 30mm (2 3/4 x 1 3/16") reference design ready to reduce the size and improve the efficiency and performance of your 3-phase brushless motor power and garden tool application in the 2S to 6S battery pack range. Implement immediate 6-step control with sensor position feedback or run your own FOC algorithms with or without sensors. Comprehensive heat management and protections are of course all integral to the solution.
