The 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.
