DESCRIPTION

The A19360 is a magnetic sensor integrated circuit (IC) that uses

giant magnetoresistance (GMR) technology to encode the speed

and direction of rotating ring magnets. Innovative algorithms

generate additional events per magnetic cycle while staying

robust to air-gap variation, to provide high-resolution rotational

data that can be used for accurate distance measurement. The

A19360 is compatible with standard ring magnets used in

automotive braking systems, and Allegro programs each IC

according to the characteristics of the magnet used.

The A19360 is available in two resolution options (4 or 8

events per cycle) and two protocol options (pulse width or AK

protocol). The four-event AK protocol option uses 28 mA speed

pulses for every event and operates continuously throughout

the full frequency range using standard bit truncation at higher

speeds. The eight-event AK protocol option uses 14 mA speed

pulses for high-resolution events and features an automatic

crossover to standard resolution at higher speeds, maximizing

the available bandwidth of the two-wire interface.

The A19360 was developed in accordance with ISO 26262

as a hardware safety element out of context, rated ASIL B(D)

(pending assessment) for use in automotive safety-related

systems when integrated and used in the manner prescribed

in the applicable safety manual and datasheet.

The A19360 is provided in a two-pin SIP package (suffix UB)

that is lead (Pb) free, with tin lead frame plating. The UB

package includes an IC and protection capacitor integrated

into a single overmolded package, with an additional molded

lead-stabilizing bar for robust shipping and ease of assembly
