Infineon expands EiceDRIVER product portfolio with its three-phase driver IC, 6EDL7141

Infineon Technologies AG expands its EiceDRIVER product portfolio of three-phase gate driver ICs with the 6EDL7141, to enable next generation of innovative and high-performance battery-powered products.

According to Infineon, popular battery-powered consumer and industrial applications, such as cordless power tools and service robots, demand reliable, cost- and energy efficient motor control solutions that meet the highest safety standards, hence the EiceDRIVER 6EDL7141.

The fully programmable solution for advanced motor control applications is packaged in a 48-pin VQFN with a 7x7mm² footprint, delivers high power density and improves overall system efficiency, according to Infineon. This is paired with the company’s power MOSFETs.

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 60V and a configurable driving current up to 1.5A, it can take a wide range of MOSFETs effectively to fit the application. The 6EDL7141 has an adjustable gate driver supply voltage setting between 7V, 10V, 12V, and 15V. Thanks to its built-in dual charge pumps, capable of maintaining the gate drive even at a low battery voltage. In addition, the smart driver is 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.

The 6EDL7141 provides the following protection features:
• Over-Current Protection (OCP), at shunt or RDS(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

The EiceDRIVER 6EDL7141 motor control three-phase gate driver IC is available in a 7×7 mm ² VQFN 48 pin package. Further information is available on Infineon’s website. The product will be showcased at Infineon’s exhibitor platform at the 2021 Applied Power Electronics Conference (APEC), which will be held virtually from 14-17 June. More information about Infineon’s participation at APEC 2021 is available here.
