Precision, High Speed, Hall-Effect Angle Sensor IC
with Integrated Diagnostics for Safety-Critical Applications
A1333
FEATURES AND BENEFITS (continued)
• Supports harsh operating conditions required for automotive
and industrial applications, including direct connection to
12 V battery
• Multiple programming / configuration formats supported
□ The system can be completely controlled and programmed
over SPI, including EEPROM writes
□ Operating temperature range from –40°C to 150°C
□ Operating supply voltage range from 4.0 to 16.5 V
♦Can support ISO 7637-2 Pulse 5b up to 39 V
• Multiple output formats supported for ease of system
integration
□ For system with limited pins available, writing and reading
can be performed over VCC and PWM pins. This allows
configuring the EEPROM in production line for a device
with only ABI/UVW and PWM pins connected.
• Stacked dual die construction to improve die-to-die matching
for systems that require redundant sensors
• Reduces magnet misalignment impact on die-to-die matching
for a given magnet diameter, relative to “side-by-side” dual
die orientation
□ ABI/UVW output provides high resolution, low latency, and
PWM for initial position
□ 10 MHz SPI for low latency angle and diagnostic
information; enables multiple independent ICs to be
connected to the same bus
□ Output resolution on ABI and UVW are selectable
