The recommended PCB layout and land pattern can be found in the AS5145B-HSSM application note (document number 000553) available on the ams OSRAM website. It provides detailed guidelines for PCB design, component placement, and soldering.
The AS5145B-HSSM has built-in magnetic field strength detection and compensation to minimize the effects of external magnetic interference. However, it's still important to follow proper shielding and layout guidelines to ensure accurate sensor operation.
The AS5145B-HSSM is rated for operation from -40°C to 125°C, but it's recommended to derate the sensor's accuracy and resolution at extreme temperatures. Consult the datasheet for detailed temperature-related specifications.
The AS5145B-HSSM is not certified for safety-critical applications, such as those requiring ASIL-D or SIL-3 compliance. However, it can be used in applications requiring functional safety, such as automotive or industrial control systems, with proper system-level design and validation.
The AS5145B-HSSM has a built-in power-on reset (POR) circuit that ensures the sensor resets correctly during power-up. It also has a brown-out detection (BOD) feature that detects voltage drops and resets the sensor if necessary. Consult the datasheet for detailed information on POR and BOD timing and behavior.
