Infineon Technologies 6EDL7141 Gate Driver IC

Infineon Technologies 6EDL7141 Gate Driver IC is designed for 3-phase BLDC or PMSM motor drive applications. The 6EDL7141 features three half-bridge drivers, each capable of driving a high side and low side N-type MOSFET. Furthermore, the device is provided with programmable dead time delays for preventing current shoot-through between HS and LS switches in normal operation.

The Infineon 6EDL7141 Gate Driver IC has separate charge pumps for low and high-side gate drivers that support a 100% duty cycle and a low voltage supply operation. The gate drivers are programmable to 7V, 10V, 12V, or 15V supplies. The slew rate of the driving signal is programmed with fine granularity to reduce EMI emissions.

The 6EDL7141 implements numerous protection features for improving application robustness during adverse conditions like monitoring of power supply voltages and system parameters.

The integrated SPI offers both detailed fault reporting and flexible parameter settings such as gain of the current sense amplifiers, slew rate control of the gate drivers, various protection features, or gate driver voltage.
