电池缓冲霍尔多圈编码器芯片

Features

• Integrated Hall sensors with auto-gain and offset control

• Adjustable performance of tracking (12,000 to 100,000 rpm) versus power consumption (2 μA to 30 μA in average)

• Configurable multiturn counting of up to 40 bits

• Octal encoder mode (singleturn) with 3-bit parallel output

• Shift-register input for singleturn position

• Shift-register output of synchronized MT/ST position

• SSI multiturn data output with error, parity, and sync. bits

• Adjustable multiturn preset value

• Supply voltage range of 3.0 V to 5.5 V

• Pin-triggered preset and boot-up from external EEPROM

• Integrated supply switching to backup battery

• Error output on overspeed, low battery, and CRC failure

Applications

• Gearless revolution counting

• Absolute end-of-shaft position sensors

• Metering applications

• Multiturn encoders
