ams AG announced that the AS8530 is the world’s first miniature power/transceiver IC to support LIN slave applications, which complies with the ISO26262 functional safety standard.
The AS8530 is a power management and communication device that includes a LIN 2.1 transceiver, a 50mA LDO to supply a local micro and a reset generator in an 8-pin SOIC 8 package. As a differentiator, the AS8530 offers a series of system management functions through a shared pin serial interface, all within the same small, 8-pin SOIC8 package.
The addition of enhanced diagnosis functions provides built-in support for the requirements of ISO26262. A two-wire serial port routed through shared Enable and TX pins allows the device to read out status registers and provide diagnosis information to the system’s microcontroller. It also supports additional features such as a window watchdog function and access to back-up registers to store data when the microcontroller shuts down.
