The EiceDRIVER product portfolio of three-phase gate driver ICs now includes the 6EDL7141, a fully programmable solution for advanced motor control applications. Packaged in a 48-pin VQFN with a 7×7-mm2 footprint, the 6EDL7141 delivers higher power density and improves overall system efficiency. Combined with Infineon’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 70 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, 10, 12 and 15 V and is able to maintain the gate drive even at low battery voltage thanks to its built-in dual charge pumps. 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 protections:
› 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 6EDL7141 motor control three-phase gate driver IC can be ordered now.
