ATS17501

Dual Output Differential Speed and Direction Sensor IC

FEATURES AND BENEFITS

DESCRIPTION

• High-speed switching bandwidth up to 40 kHz

• Two independent output channels with options for high

resolution XOR speed, pulse, and direction protocol

• ASIL B(D) compliant (ISO 26262), assessment pending

• Optional fault detection output protocol

• Immune to common external magnetic disturbance

• EEPROM enables factory traceability throughout product

life cycle

TheATS17501 is a single IC solution designed for rotational

position sensing of a ferrous gear target found in automotive

and industrial electric motor applications (often with specific

application and safety requirements). The IC is housed in an

SG package that incorporates a rare-earth magnetic pellet for

ease of manufacturing, consistent application performance

over temperature, and enhanced reliability.

ThreeHallelementsareincorporatedtocreatetwoindependent

differential channels. These inputs are processed by digital

circuits and robust algorithms designed to eliminate the

detrimental effects of magnetic and system offsets, and to

address false output transitions caused by target vibrations

in electric motors at startup and low speed operation. The

differential signals are used to produce a highly accurate

speed output and, if desired, provide information on the

direction of rotation.

• Ideally suited for asynchronous electric motor applications

Advanced calibration techniques are used to optimize signal

offset and amplitude. This calibration, combined with the

digital tracking of the signal, results in accurate switch points

over air gap, speed, and temperature.

PACKAGE:

The IC can be programmed for a variety of applications

requiring dual-phase gear speed and position signal

information or simultaneous high-resolution gear speed

and direction information. It can be configured to enable

Fault Detection mode for ASIL B(D) utilization (assessment

pending).

4-Pin SIP

(suffix SG)

The ATS17501 SG package is a lead (Pb) free 4-pin SIP

package with an integrated back-biasing magnet and a 100%

matte-tin-plated lead frame.
