SC69431DC

Hall Effect Angular Position Sensor

Based on IMC 3D sensing principle、Offers Multiple Output Modes

The SC69431 is a new generation of position sensor chip based on the principle of IMC 3D magnetic induction. The chip integrates two pairs of perpendicularly placed Hall chip arrays and a magnetic collector. The signal is amplified by a preamplifier and sampled by the internal analog-to-digital converter circuitry, and the chip's proprietary DSP circuitry performs the angular algorithms, and finally outputs absolute angular, linear, and 3D positions through a variety of interface formats.

Characteristics and advantages

Based on IMC 3D sensing principle, supporting angle and linear displacement detection in selectable XY, XZ, or YZ planes, as well as 3D position detection in XYZ space.

Wide operating temperature range:-40°C to 160°C.

Selectable output interfaces: Analog voltage, PWM (Pulse-Width Modulation), digital SPI, SAE J2716-compliant SENT, and 2-wire current-mode PSI5 (V2.3).

Programmable linear transfer characteristic, configurable via arbitrary 4/8 points or 16/32-segment piecewise linear curves.

32-bit programmable user ID for device identification and traceability.

Comprehensive on-chip diagnostic functions.

Wire break diagnosis (VDD open, VSS open).

Over-current and over-voltage protection; under-voltage detection.

AEC-Q100 Grade0 qualified

ISO26262 ASIL-B qualified

Package options: Single-channel SOP-8, dual-channel redundant TSSOP-16, and SIP-3. All packages are lead-free and compliant with EU RoHS requirements.
