Infineon — EiceDRIVER™ 2ED4820-EM Smart High-Side MOSFET Gate Driver

Infineon 2ED4820-EM Smart High-Side MOSFET Gate Driver

Featuring an extended supply voltage range of 20 - 70 V

The Infineon EiceDRIVER™ 2ED4820-EM smart high-side N-channel MOSFET Gate driver features two outputs controlled via SPI and an integrated powerful charge pump that allows external MOSFETs to stay continuously on.

Thanks to the enhanced turn-on and turn-off ability of the driver, the number of MOSFETs could be easily scaled up to manage large currents in the order of several hundred amps while ensuring a fast switch on and off. The MOSFETs could be controlled in a back-to-back configuration either common mode or common source.

The 2ED4820-EM gate driver features an integrated current sense amplifier that supports high-side and even low-side current measurement with a dedicated monitoring output. The 2ED4820-EM comes along with several latching failure detections, to implement protections for the external MOSFETs, the load, and the power source. Parameters can be adjusted by SPI; monitoring data, configuration, warning, and failure detection registers can be read.
