Magnetic position sensor IC for space-constrained applications
ams’ AS5200L uses dual dies that can be paired with a single small target magnet while providing identical measurement outputs from each die. Separate package pins are provided for each die to prevent an electrical fault in the device from affecting both dies.
The AS5200L is housed in an MLF-16 package and is suited for automotive system designers seeking to implement robust, accurate rotary position sensing in vehicle electrification applications with tight space constraints.
An I2C interface allows for easy programming of parameters by a host MCU, and the sensor can use the I2C interface to output the angular measurements, or they can be output as a PWM signal. Angle measurements are supplied in 12-bit resolution, and the maximum error attributable to non-linearity is a maximum ±1°.
The sensor measures rotation over a full 0° to 360° rotation by default. A smaller range may be set by programming a start and stop position into the chip’s OTP memory.
