AI Technical Summary
Existing automotive antenna short-circuit protection systems rely on microprocessors and software, resulting in high system complexity, increased costs, and increased dark current, making it impossible to achieve real-time monitoring and protection.
A short-circuit protection circuit composed of transistors is used to realize instant short-circuit protection between the antenna and components through hardware. It includes a first short-circuit protection circuit, a second short-circuit protection circuit and an antenna status detection circuit. The transistors are used to cut off the overvoltage or overcurrent path by turning on and off.
It enables real-time monitoring and protection without software support, reducing system complexity and cost while ensuring stable antenna operation.
