Fully programmable three-phase driver IC

Infineon Technologies AG has expanded its EiceDRIVER product portfolio of three-phase gate driver ICs with the 6EDL7141. This fully programmable solution for advanced motor control applications is supplied in a 48-pin VQFN with a 7mm x 7mm² footprint, provides higher power density and enhances overall system efficiency. Combined with the company’s power MOSFETs, customers can now develop a complete end solution employing the company as a one-stop shop.

The device provides an SPI interface for gate drive outputs configuration and an integrated power supply and dual charge pumps to provide all system functions. With an operating voltage covering from 5.5V to 60V and a configurable driving current up to 1.5A, it can drive an extensive range of MOSFETs effectively to fit the application. The device provides an adjustable gate driver supply voltage setting between 7V, 10V, 12V and 15V. Due to its built-in dual charge pumps, it can maintain the gate drive even at low battery voltage. Also, the smart driver is provided with an adjustable gate drive configuration, with numerous current levels and timing options to control the slew rate and minimise system EMI. All of the device settings can be simply changed with the available GUI.
