At present, advanced intelligent vehicles are generally equipped with Advanced Driving Assistance System (ADAS). The application of ADAS is the key to realize the active safety of automobiles and must have high availability. In contrast, the landing of automatic driving technology is more challenging, because the automatic driving function requires the vehicle itself to complete emergency operation in case of failure. This puts forward higher requirements for the automobile power distribution system, and requires the introduction of safety components to ensure that the system can quickly achieve fault isolation within 100 microseconds. Because the fuse can not meet this requirement, it is necessary to consider partial or comprehensive electrification transformation of the automobile power distribution system. In addition, there will be more and more applications on intelligent vehicles that can improve the comfort of drivers and passengers.
目前，先进的智能汽车普遍搭载了高级驾驶辅助系统（ADAS）。ADAS应用是实现汽车主动安全的关键，必须具备高可用性。相比之下，自动驾驶技术的落地则更具挑战性，因为自动驾驶功能要求在发生故障时亦由车辆自身完成应急操作。这给汽车配电系统提出了更高要求，要求引入安全元件，以确保系统在100微秒内快速实现故障隔离。由于保险丝无法满足这一要求，需要考虑对汽车配电系统进行部分或全面的电气化改造。此外，智能汽车上还会出现越来越多可以提高驾驶员和乘客舒适度的应用。
The power distribution system supplies power for these applications, allowing electrical energy to flow from batteries or motors to various loads in the vehicle in a highly safe and controllable manner. One of the biggest challenges facing designers today is to reduce the cost, length, weight and complexity of the harness. In order to help designers solve this problem, Infineon launched an intelligent high-voltage side MOSFET grid driver EiceDRIVE 2ED2410-EM with integrated circuit protection function for 12 V/24 V automotive applications. The grid driver is the ideal partner of Infineon 40/60 V OptiMOS MOSFET.
配电系统为这些应用供电，让电能以高度安全和可控的方式从电池或者电机流向汽车中的各种负载。如今，设计师面临的最大挑战之一就是降低线束的成本、长度、重量和复杂性。为了帮助设计师解决这一难题，英飞凌面向12 V / 24 V汽车应用推出了具有集成线路保护功能的智能高压侧MOSFET栅极驱动器——EiceDRIVER 2ED2410-EM，该栅极驱动器是英飞凌40/60 V OptiMOS MOSFET的理想搭档。
The gate driver has two output channels, which is suitable for two different MOSFET structures: a common source stage or a common drain back to back configuration with a pre charging path. The enhanced driver switch functionality allows it to easily increase the number of MOSFETs in order to control greater load currents. Even when the current reaches hundreds of amperes, it can be quickly disconnected in microseconds, while traditional fuses need to wait several milliseconds to open. In addition, during the period from short circuit to disconnection of fault load, the device can operate normally at a voltage as low as 3V.
该栅极驱动器具有两路输出通道，适用于两种不同的MOSFET结构：具有预充电路径的共源级或共漏极背对背配置。增强的驱动器开关功能令其能够轻松地增加MOSFET的数量，以便控制更大的负载电流。即使电流达到数百安培时，它也能在微秒内快速断开，而传统的保险丝需要等待几毫秒才能断开。此外，从短路到断开故障负载这段时间内，该器件能够在低至3V的电压下正常运行。
EiceDRIVER 2ED2410-EM has three analog measurement interfaces and four integrated comparators to provide protection, which can provide flexible and rich solutions to meet various functional requirements, including adjustable I-t line protection, over-current protection, over-voltage/undervoltage protection, etc. It can measure bi-directional current, monitor drain source voltage, and determine open circuit of output load.
EiceDRIVER 2ED2410-EM具有三个模拟测量接口和四个提供保护的集成比较器，可提供灵活且丰富的解决方案，以满足各种功能要求，包括可调节的I-t线路保护、过流保护、过/欠电压保护等。它可以测量双向电流并监测漏源电压，确定输出端负载开路等情况。
The adjustable line protection function is helpful to select the wire section as small as possible for the corresponding load. In the past, considering the tolerance and aging effect of traditional fuses, the wire diameter must be up to 30% more than the actual demand. The device has an extremely low quiescent current loss of a few tenths of an ampere, which can minimize the automatic discharge of the battery when the vehicle is parked.
可调节的线路保护功能有助于为相应的负载选择尽可能小的电线截面。过去，考虑到传统保险丝的公差和老化效应，电线直径必须比实际需求多出高达30%的余量。该器件具有零点几微安的极低静态电流损耗，可尽量减少车辆停放时电池的自动放电。
