ATA5293数据手册Microchip中文资料规格书

描述 Description

An LF antenna driver device for passive entry/go (PEG) systems. It can drive up to eight low-frequency antennas (coils) to provide a wake-up and initialization channel to the key fob. Each driver is programmable up to a peak current of 1A (independent of battery voltage) and adjustable in 18 steps.
