A1363

Low Noise, High Precision, Programmable Linear Hall Effect Sensor IC

With Advanced Temperature Compensation and High Bandwidth (120 kHz) Analog Output

DESCRIPTION

FEATURES AND BENEFITS

• Proprietary segmented linear interpolated temperature

compensation (TC) technology provides a typical

accuracy of 1% across the full operating temperature

range

• Customer programmable, high resolution offset and

sensitivity trim

• Factory programmed sensitivity and quiescent

output voltage TC with extremely stable temperature

performance

• High sensitivity Hall element for maximum accuracy

• Extremely low noise and high resolution achieved via

proprietary Hall element and low noise amplifier circuits

• 120 kHz nominal bandwidth achieved via proprietary

packaging and chopper stabilization techniques

• Patented circuits suppress IC output spiking during fast

current step inputs

The Allegro™ A1363 programmable linear Hall-effect

current sensor IC has been designed to achieve high accuracy

and resolution without compromising bandwidth. The goal

is achieved through new proprietary linearly interpolated

temperature compensation technology that is programmed

at the Allegro factory and provides sensitivity and offset that

are virtually flat across the full operating temperature range.

Temperature compensation is done in the digital domain with

integratedEEPROMtechnology, withoutsacrificingtheanalog

signal path 120 kHz bandwidth, making this device ideal for

HEVinverter,DC-to-DCconverter,andelectricpowersteering

(EPS) applications.

thatisproportionaltotheappliedmagneticfield. Thecustomer

can conFigure the sensitivity and quiescent (zero field) output

voltage through programming on the VCC and output pins, to

optimize performance in the end application. The quiescent

output voltage is user-adjustable around 50% of the supply

voltage, V_CC, and the output sensitivity is adjustable within

the range of 0.6 to 14 mV/G.
