EVAL_6EDL7141_1KW_36V for battery-powered
applications using 6EDL7141 smart gate driver

About this document

Scope and purpose
This document describes the functionalities of the EVAL_6EDL7141_1KW_36V motor drive board for battery-
powered brushless DC (BLDC) motor drives; used in applications such as gardening tools up to 1 kW. The
evaluation board can support motors with Hall sensors for rotor position sensing, or without Hall sensors.
This solution combines a high-performance three-phase smart driver IC and the motor inverter power stage
with two power MOSFETs of BSC012N06NS in parallel for each phase. You can use your own MCU to design the
controlling unit by using a daughterboard to connect to the evaluation board using a MADK connector.
Intended audience
This document is intended for design engineers, applications engineers, and students who address the market
for gardening tools and other battery-powered motor drive applications, aimed to provide a high-performance
system solution as well as to reduce system costs.

  • Page 32 EVAL_6EDL7141_1KW_36V for battery-powered applications using 6EDL7141 smart gate driver System design The PCB layout is optimized to minimize radiated EMI. This is achieved by keeping the loops carrying the switching currents as small as possible. The HF switching current loops are illustrated in the following. Note that during the switching transition, the high-side gate drive loop current returns to the main ground rather than back to the gate driver as in a conventional high-side driver.
