A1330

Programmable Angle Sensor IC

with Analog and PWM Output

FEATURES AND BENEFITS

DESCRIPTION

• Contactless 0° to 360° angle sensor IC, for angular

position, rotational speed, and direction measurement

• Single and dual die options available in same package

• Non-volatile memory (EEPROM) for use in application

trimming/calibration

TheA1330 is a 360° angle sensor IC that provides contactless

high-resolutionangularpositioninformationbasedonmagnetic

Circular Vertical Hall (CVH) technology. It has a system-on-

chip (SoC) architecture that includes: a CVH front end, digital

signal processing, and an analog output driver. It also includes

on-chip EEPROM technology, capable of supporting up to

100 read/write cycles, for flexible end-of-line programming

of calibration parameters. Broken ground wire detection and

user-selectable output voltage clamps make the A1330 ideal

for high-reliability applications requiring high-speed 0° to

360° angle measurements.

• Circular Vertical Hall (CVH) technology provides a

single-channel sensor system with air gap independence

• Angle Refresh Rate (output rate) configurable between

25 and 3200 µs through EEPROM programming

• Customer-programmable output clamp levels provide

short-circuit diagnostic capabilities

• Open-circuit detection on ground pin (broken wire)

• Undervoltage lockout for V_CCbelow specification

• Fine angle scaling for short-stroke applications

• Missing Magnet Error flag for notifying controller of low

magnetic field level

The A1330 provides adjustable internal averaging, allowing

response time to be traded for resolution. This is ideal for

applicationsoperatingatlowrotationalvelocitiesrequiringhigh

precision. For higher RPM applications, the A1330 provides

industry-leading analog response time when no averaging is

enabled.

• EEPROM programmable angle reference (0°) position

and rotation direction (CW or CCW)

• AEC-Q100 automotive qualified

With programmable angle scaling, the A1330 supports

applications requiring short angular displacements, while

maintaining full dynamic range on the output. Programmable

minimum and maximum angle thresholds allow diagnosis of

mechanical failures.

PACKAGE: 8-pin TSSOP (LE package)

The A1330 is available as either a single or dual die option,

in an 8-pin TSSOP. The package is lead (Pb) free with 100%

matte-tin leadframe plating.
