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 VCC below 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.
