Infineon recently released a new three-phase gate driver IC for the next generation of innovative and high-performance battery-powered products. Packaged in a 48-pin VQFN with a 7x7 mm² footprint, 6EDL7141 delivers higher power density and improves overall system efficiency for advanced motor control applications. Combined with the company’s market-leading power MOSFETs, customers are now able to develop their complete end solutions using Infineon as their one-stop-shop.
The 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. The 6EDL7141 has an adjustable gate driver supply voltage setting between 7 V, 10 V, 12 V and 15 V. Thanks to its built-in dual charge pumps, it is able to maintain the gate drive even at 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.
In addition, to provide the highest level of system reliability against fault conditions, the 6EDL7141 provides the following protection features:
- 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
The EiceDRIVER 6EDL7141 motor control three-phase gate driver IC is available in a 7x7 mm² VQFN 48 pin package. More information please visit www.infineon.com/6edl7141.
