A19520

Vibration-Tolerant Hall-Effect

Transmission Speed and Direction Sensor IC

FEATURES AND BENEFITS

DESCRIPTION

• Differential Hall-effect sensor measures ring magnets

and ferrous targets with inherent stray field immunity

• SolidSpeed Digital Architecture™ provides robust,

adaptive performance with advanced algorithms that

provide vibration immunity over the full target pitch

• Integrated solution includes a capacitor in a single

overmolded miniature package

• ISO 26262:2011 ASIL B with integrated diagnostics and

certified safety design process

• Two-wire current source output pulse-width protocol

supporting speed, direction, and ASIL error reporting

• EEPROM enables factory traceability

The A19520 is an advanced vibration-tolerant Hall-effect

integrated circuit (IC) that measures the speed and direction

of rotating targets. This sensor IC can directly measure ring

magnets or be back-biased with a magnet to measure ferrous

targets. The package features an integrated capacitor for

electromagnetic compatibility (EMC).

The A19520 employs intelligent algorithms that allow stable

operation during vibration and highly dynamic air gap

environmentscommontotransmissionapplications.Inaddition,

the A19520 differential sensing offers inherent rejection of

interfering common-mode magnetic fields.

Integrated diagnostics are used to detect an IC failure that

impacts the output protocol’s accuracy, providing coverage

compatible with ASIL B compliance.

PACKAGE:

2-Pin SIP

(suffix UB)

The A19520 is provided in a 2-pin miniature SIP package

(suffix UB) that is lead (Pb) free, with tin leadframe plating.

The UB package includes an IC and capacitor integrated into

a single overmolded package, with an additional molded

lead-stabilizing bar for robust shipping and ease of assembly.
