Allegro MicroSystems is expanding its robotics portfolio with position sensors and a 48-V PMIC for humanoid robots. The A81481 combines two step-down converters, five LDO outputs, and ASIL-D-compliant diagnostics in a 6 × 6 mm (0.24 × 0.24 inch)  package, reducing space requirements and bill-of-materials costs by approximately 50 percent. The CT310 angle sensor achieves sub-degree accuracy in a 2 × 2 mm (0.08 × 0.08 inch) DFN package.
