AAS33051

Precision Angle Sensor IC with Incremental and

Motor Commutation Outputs and On-Chip Linearization

FEATURES AND BENEFITS

DESCRIPTION

The AAS33051 is a 360° angle sensor IC that provides

contactlesshigh-resolutionangularpositioninformationbased

on magnetic circular vertical Hall (CVH) technology. It has a

system-on-chip (SoC) architecture that includes: a CVH front

end, digital signal processing to calculate the angular position

information,andmultipleoutputformats:serialprotocol(SPI),

pulse-widthmodulation(PWM),andeithermotorcommutation

(UVW) or encoder outputs (A, B, I). It also includes on-chip

EEPROM technology, capable of supporting up to 100

read/write cycles, for flexible programming of calibration

parameters.TheAAS33051isidealforautomotiveapplications

requiring 0° to 360° angle measurements, such as electronic

powersteering(EPS), electronicpowerbraking(EPBorIDB),

transmission actuators, and BLDC pumps.

• Contactless 0° to 360° angle sensor IC, for angular

position, rotational speed, and direction measurement

□ Capable of sensing magnet rotational speeds targeting

12.5-bit effective resolution with 300 G field; higher

effective resolution possible at higher field strengths

□ Circular Vertical Hall (CVH) technology provides a

single channel sensor system, with air gap independence

• On-chip 32 segment linearization to improve angle accuracy

□ Reduces impact of magnet to sensor misalignment

□ Reduces impact of imperfect magnetization of target

magnet

• Developed as a Safety Element out of Context (SEooC)

in accordance with ISO 26262:2011 requirements for

hardware product development for use in safety-critical

applications (pending assessment)

TheAAS33051includeson-chip32segmentlinearization.This

canbeusedtocalibrateouterrorsduetomisalignmentbetween

the magnet and the sensor or imperfect magnetization of the

target magnet (which can present itself as a misalignment of

the magnet to the sensor).

□ Single die version designed to meet ASIL B

requirements when integrated and used in conjunction

with the appropriate system-level control, in the

manner prescribed in the AAS33051 Safety Manual

□ Dual die version designed to meet ASIL D

The AAS33051 supports customer integration into safety-

critical applications.

requirements when integrated and used in conjunction

with the appropriate system-level control, in the

manner prescribed in the AAS33051 Safety Manual

The AAS33051 is available in a dual-die 24-pin eTSSOP and

a single-die 14-pin TSSOP package. The packages are lead

(Pb) free with 100% matte-tin leadframe plating. The 1 mm

thin package reduces the minimum air gap between the CVH

transducer and the target magnet. The AAS33051 device is

pin-compatible with the A1339 to enable easy migration.
