Infineon launches fully programmable, three-phase driver IC

Increasingly popular battery-powered consumer and industrial applications — such as cordless power tools and service robots — demand reliable, cost-effective, and energy-efficient motor control solutions that meet the highest safety standards.

To enable the next generation of innovative and high-performance battery-powered products, Infineon Technologies is expanding its EiceDRIVER product portfolio of three-phase gate driver ICs.

The fully programmable 6EDL7141 solution for advanced motor-control applications is packaged in a 48-pin VQFN with a 7×7 mm² footprint, delivering higher power density and improving overall system efficiency.

Combined with the company’s power MOSFETs, customers are now able to develop their complete end solutions using Infineon as their one-stop-shop.

The EiceDRIVER 6EDL7141 features an SPI interface for gate drive outputs configuration, as well as an integrated power supply and dual-charge pumps to supply all system functions. With an operating voltage ranging from 5.5 to 60 V and a configurable driving current up to 1.5 A, it can drive a wide range of MOSFETs effectively to fit the application.

Additionally it offers an adjustable gate-driver supply voltage setting, between 7 , 10 , 12, and 15 V. Thanks to its built-in dual charge pumps, it’s able to maintain the gate drive at a low battery voltage. The smart driver is also equipped with an adjustable gate-drive configuration, with several current levels and timing options to control the slew rate and minimize system electromagnetic interference (EMI).

All of the 6EDL7141 settings can be easily changed with the available GUI.

To provide the highest level of system reliability against fault conditions, the 6EDL7141 also provides:

Over-current protection (OCP), at shunt or R _DS(on), DVDD LDO OCP, buck-converter OCP (PCMC)
Under-voltage lockout (UVLO) on PVDD, gate-driver supply, DVDD LDO
Temperature warning and shutdown
Configurable watchdog
Rotor locked detection based on hall sensor inputs
Memory fault
