Automotive Failsafe System Ic

The ATA6814 is a monolithically-integrated multi-functional IC designed in Atmels state-of-the-art 0.8 m BCDMOS technology. With its built-in driver stages, voltage supplies and monitoring functions, it is an ideal cost saving failsafe system IC. The Communication with an external Microcontroller is provided by an 8-bit SPI Interface Four protected and Current Limited driver stages are available to control relays and additionally there is a Gate driver including Charge Pump and bootstrap to control an external FET Three LEDs for status information CAN be controlled via three separate outputs: The high-side driver at pin OUTP has monitoring functions for overcurrent and current threshold. The low-side drivers at the pins WLN and OUTN also have monitoring functions for overcurrent, current threshold, and voltage monitoring. Two internal bandgap references control and monitor two independent 5V supply voltages. In standby mode the internal IC-supply is provided by one of them; the other one is switched off, in order to reduce the power consumption to a minimum. All internal blocks are supplied by a spe- cific internal voltage Regulator The system supply voltage and all internally-generated voltages are monitored and in case of over or undervoltage all drivers are switched off. Via the SPI the system supply voltage CAN be switched to provide power for external components. By ATMEL Corporation
