A1363
Low Noise, High Precision, Programmable Linear Hall Effect Sensor IC
With Advanced Temperature Compensation
And High Bandwidth (120 kHz) Analog Output
Features and Benefits (continued)
• Open circuit detection on ground pin (broken wire)
• Undervoltage lockout for VCC below specification
• Selectable sensitivity range between 0.6 and 14 mV/G through
use of coarse sensitivity programming bits
• Ratiometric sensitivity, quiescent voltage output, and clamps
for interfacing with application A-to-D converter (ADC)
• Precise recoverability after temperature cycling
• Output voltage clamps provide short circuit diagnostic
capabilities
• Wide ambient temperature range: –40°C to 150°C
• Immune to mechanical stress
• Extremely thin package: 1 mm case thickness
• AEC Q-100 automotive qualified
Description (continued)
output stage, and a proprietary, high bandwidth dynamic offset
cancellation technique. These advances in Hall-effect technology
work together to provide an industry leading sensing resolution at
the full 120 kHz bandwidth. Broken ground wire detection as well as
user-selectable output voltage clamps also are built into this device,
for high reliability in automotive applications.
Device parameters are specified across an extended ambient
temperature range: –40°C to 150°C. The A1363 sensor IC is
provided in an extremely thin case (1 mm thick), 4-pin SIP (single
in-line package, suffix KT) that is lead (Pb) free, with 100% matte
tin lead frame plating.

2 Allegro recommends against changing Coarse Sensitivity settings when programming devices that will be used in production. Each
A1363 has been Factory Temperature Compensated at a specific Sensitivity Range and changing coarse bits setting could cause sen-
sitivity drift through temperature range ,ΔSensTC , to exceed specified limits..
