protection through clamping, anti-pulse, and high voltage detection. This ensures the product to
operate normally under high voltage.
Auto power transient pulse: When the vehicle starts or is running, it will generate high-voltage
transient pulse with a range of hundreds of volts. If the product's circuit is not well designed, it is
very easy to get damaged, and can't be used. Through multistage transient pulse protection and
anti high-voltage surge protection, the product's power circuit is well protected, and it can operate
stably.
Electromagnetic immunity: When the vehicle starts, the clock, RF, display screen and USB are very
easy to be interfered by electric spark, which causes the product to operate unstably. Through PCB
layout and ground wire handling, the product can work stably under interfered environment.
Anti static: The vehicle product's working condition is complex. It is very easy to be influenced by
static, which causes damage to the product's peripheral interfaces. Through ESD protection on
circuit and ground wire handling, the static in the range of 8KV-15KV won't cause damage to
product. This ensures the product's stability under complex working condition.
