Designers can now achieve ASIL compliance for automotive camera modules with the MAX20087 dual/quad camera protector IC from Maxim Integrated Products, Inc. According to the company, this is the industry’s only ASIL B- to ASIL D-compliant camera protector IC with integrated I2C-based diagnostics, making it ideal in supporting multiple automotive cameras in advanced driver assistance systems (ADAS). A single MAX20087 supports four cameras simultaneously, while four of the devices in parallel on the same bus supports 16 cameras, protecting each output individually from short-to-battery, short-to-ground and overcurrent conditions.
The MAX20087 dual/quad device is an integrated camera power protector IC that can be plugged into a fusion electronic control unit (ECU). It enables fault mitigation circuitry by requiring minimal external components. In addition to a built-in self-test (BIST), an integrated 8-bit analog-to-digital converter (ADC) monitors current, voltage, and supply readings as required for ASIL compliance. With this IC, designers can isolate faults on cameras powered from a single power supply, while providing diagnostic fault information via I2C. As a dual/quad channel device, it provides up to 600mA protection switches in a 4mm x 4mm, 20-pin side wettable TQFN package.
