Miniature Power/Transceiver IC from ams
August 25, 2013
The AS8530 miniature power/transceiver IC to support LIN slave applications is offered by ams AG, Unterpremstaetten, Austria. It is a management and communication device that includes a LIN 2.1 transceiver, a 50 mA LDO, and a reset generator in an 8-pin SOIC 8 package, and as a differentiator offers system management functions through shared pin serial interface. A two-wire serial port routed through shared Enable and TX pins allows the device to read out status registers and provide diagnostics. These features are crucial in the design of ISO26262-compliant systems, in order to cease operation safely when in a fault condition. The AS8530 is suitable for any LIN-networked sensor and actuator slaves. The onchip LDO provides a factory-selectable 3.3 V or 5 V output. The chip also offers a reset generator and an output voltage monitor with chip ID for traceability. Modes include normal operating, power-saver standby, and sleep.
