2ED4820-EM
48 V smart high-side MOSFET gate driver with SPI for automotive applications
The EiceDRIVERTM 2ED4820-EM is a smart high-side N-channel MOSFET Gate driver with two outputs controlled via SPI. The integrated powerful charge pump 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 integrated current sense amplifier 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.
