APS11500 Overview
APS11500 devices are two-wire planar Hall-effect sensor integrated circuits (ICs) developed in accordance with ISO 26262. They include internal diagnostics and support a functional safety level of ASIL A. The enhanced two-wire current-mode interface provides interconnect open/short diagnostics and adds a Safe State to municate diagnostic information while maintaining patibility with legacy two-wire systems.
