ams OSRAM 1 Axis Surface Hall Effect Sensor -0.3 V to 7 V, UVW, SPI, PWM Interface, TSSOP 14-Pin AS5147U-HTSM

ams OSRAM AS5147U-HTSM is a high-resolution rotary position sensor designed for precise absolute angle measurement over 360 degrees. It operates with a supply voltage range from -0.3 V up to 7 V, featuring multiple output interfaces including UVW, SPI, and PWM in a compact 14-pin TSSOP package.

The sensor incorporates advanced dynamic angle error compensation (DAEC™) technology that delivers nearly zero latency at high rotational speeds, making it ideal for fast-moving automotive and industrial applications. Its dynamic filter system (DFS™) enhances signal quality by reducing noise during low-speed rotations. The device’s robust construction effectively suppresses interference from homogenous external stray magnetic fields, ensuring consistent and stable readings.

Communication is facilitated via a standard 4-wire SPI interface with CRC protection, allowing a host microcontroller to read 14-bit absolute angle position data and program non-volatile device settings securely without requiring dedicated programming tools. Incremental movements are available through ABI signal outputs that provide a resolution of up to 16989 steps or 4096 pulses per revolution, enabling precise control and position tracking in demanding systems.

The AS5147U-HTSM sensor supports a wide ambient operating temperature range from -40°C to 150°C, making it suitable for harsh automotive and industrial environments. It complies with key industry standards such as AEC-Q100 Grade 0 for automotive use and ISO26262 functional safety. Built using reliable CMOS technology, it delivers a supply current of 98 mA within a compact 5 mm length TSSOP package designed for surface mount installations.
