Magnetic Position Sensors Support ISO26262 In SiP Format
ams AG

Embarking as the company’s first magnetic position sensors developed using the automotive industry’s program for ISO26262 safety compliance, the AS5170 and AS5171 magnetic position sensors are also the company’s first to come in a System-in-Package (SiP) format. Both sensors were developed as Safety Element out of Context (SEooC) devices as defined in the ISO26262 functional safety standard. The diagnostic system built into the AS517x series tests the entire device, from the Hall sensor front end, through the DSP engine which converts raw measurements of magnetic field strength into sine and cosine vectors, to the back-end interfaces and pins. The AS5171 comes in an SiP format, which integrates the sensor die and capacitors in a single, encapsulated three-pin package. The SiP offers improved ESD and EMC performance, as well as enhanced supply protection. The supply and output pins are protected against over-voltages up to +20V. The supply pin also offers -20V of protection against reverse polarity. The AS5171A provides an analog output, and the AS5171B provides a digital output, which may be programmed either as a PWM interface or as a SENT-compliant interface. The analog AS5170A and digital AS5170B ICs are housed in an 8-pin SOIC package. The AS5170 and AS5171 magnetic position sensors are available now in production volumes. Unit pricing is $2.64 (AS5170) and $2.87 (AS5171) each/1,000. For more details, go to:
