Infineon presents two evaluation boards, the EVAL-6ED2742S01QM1 and EVAL-2ED2742S01, tailored for battery-supplied BLDC motor control applications. These boards serve as invaluable tools during the design-in process, offering a comprehensive platform for evaluating and measuring characteristic curves, as well as verifying datasheet specifications.
The EVAL-6ED2742S01QM1 kit comprises a three-phase inverter power board equipped with a 160 V rated MOTIX™ 6ED2742S01Q three-phase gate driver, driving six 150 V rated OptiMOS™ MOSFETs BSC074N15NS5. Notably, it features integrated bootstrap diodes and protection functionalities such as undervoltage lockout, overcurrent protection, fault communication, and automatic fault clearance. The output drivers are designed with a high-pulse current buffer stage to minimize driver cross-conduction, and a current-sense operational amplifier (CSA) with selectable gain is integrated between the VSS and COM.
On the other hand, the EVAL-2ED2742S01 kit includes a three-phase inverter power board with a 160 V rated MOTIX 2ED2742S01Q half-bridge SOI gate driver driving six 150 V rated OptiMOS MOSFETs. This board also incorporates integrated bootstrap diodes and undervoltage lockout protection.
Both the 6ED2742 and 2ED2742 boards are fully qualified for industrial applications based on the relevant tests of JEDEC78/20/22. Additionally, they feature an M1 connector for interfacing with the iMOTION™ modular application design kit (MADK) control card (EVAL-M1-101T).
In conclusion, Infineon's EVAL-6ED2742S01QM1 and EVAL-2ED2742S01 evaluation boards represent a significant advancement in the realm of battery-powered BLDC motor-drive applications, providing a robust platform for thorough evaluation and verification in a laboratory environment, all while adhering to stringent safety requirements.
