Smart analog high-side MOSFET gate driver for 12 V/ 24 V automotive applications
The EiceDRIVER™ APD 2ED2410-EM is a smart high-side N-channel MOSFET gate driver with two outputs controlled via logic pins designed for the new upcoming automotive power distribution architectures for 12 and 24 V board nets.
The integrated boost converter allows external MOSFETs to stay continuously on and operational also at cold cranking conditions down to 3 V. Due to the efficiency of the boost converter the supply current in idle and normal mode is in the range of µA, which is beneficial if loads need to be supplied during the vehicle is parked (key off mode). 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 fast switch on and off within µs.
The 2ED2410-EM has three analog measurement interfaces and four integrated comparators for protection purposes, allowing flexible and versatile solutions for various E/E architecture requirements, for example: adjustable I-t wire protection, overcurrent protection, over/undervoltage protection and more.
