High-speed rotary position sensor

1 July 2015 Analogue, Mixed Signal, LSI

The AS5147P from ams is a magnetic rotary position sensor IC which offers high-speed performance in automotive applications compatible with the requirements of the ISO26262 functional safety standard. Providing accurate absolute and incremental measurement outputs at speeds up to 28 000 rpm, it is ideal for safety-critical applications and draws on

patented DAEC (Dynamic Angle Error Correction) technology to deliver accurate position measurements even at extremely high rotation speeds. As a result, the device’s angle error is a negligible 0,02° at 1700 rpm, 0,17° at 14500 rpm and 0,34° at 28000 rpm. The DAEC function also enables the device to refresh its measurement output every 1,9 μs.
