Infineon MOTIX™ 6EDL7141 Three-Phase Smart Gate Drive Controller IC

For battery supplied BLDC motor control. Single shunt evaluation board also available

The Infineon MOTIX™ 6EDL7141 is the latest 3-phase motor control gate driver IC that enables development of high performance battery operated products using BLDC or PMSM motors.

With over 50 programmable parameters using built-in digital SPI interface, the MOTIX™ 6EDL7141 is fully configurable to drive a wide range of MOSFET’s to yield the best possible system efficiency.

The MOTIX™ 6EDL7141 is also designed for maximum flexibility

With an operating voltage from 5.5-60 V and configurable gate drive sink and source current up to 1.5 A, the MOTIX™ 6EDL7141 has the ability to drive a wide range of MOSFETs effectively to best fit the application. It has adjustable gate driver supply voltage setting between 7 V, 10 V, 12 V and 15V even at low battery voltage thanks to built-in dual charge pumps.

The Infineon MOTIX™ 6EDL7141 also has adjustable gate driver parameters to enable control of the slew rate to minimize system EMI. All of the MOTIX™ 6EDL7141 settings can be quickly changed with the available easy-to-use GUI. The integrated buck regulator requires only an external capacitor and inductor to provide power for both the microcontroller and the Hall sensors in the motor, further reducing peripheral components and required PCB area.

In addition, with a full suite of system protection features such as OCP, UVLO, over-temperature, and locked rotor detection, this dedicated motor controller will increase reliability and robustness in severe operating fault conditions.
