EiceDRIVER 6EDL7141 Three-Phase Driver IC

Infineon Technologies has added a new fully programmable three-phase gate driver IC into their EiceDRIVER product portfolio to provide a cost- and energy-efficient motor control solution for battery-powered consumer and industrial products. Available in a 48-pin VQFN package with a 7×7 mm² footprint,  the new gate driver IC delivers higher power density and improves overall system efficiency.

The EiceDRIVER 6EDL7141 IC comes with a SPI interface for gate drive outputs configuration, 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 drive a wide range of MOSFETs effectively. Moreover, the new gate driver IC has an adjustable gate driver supply voltage setting between 7V, 10V, 12V and 15V, and equipped with an adjustable gate drive configuration, with several current levels and timing options to control the slew rate and minimize system EMI.

In addition, the new gate driver IC offers following protection features against fault conditions:

  • 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 IC 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.  For more details about the product, visit: www.infineon.com/6edl7141.
