一种内嵌于DSP芯片的高耐压ECAN驱动器
High-voltage-tolerant ECAN driver embedded in the DSP chip
摘要
Abstract
A high-voltage-tolerant ECAN(enhanced controller area network)driver embedded in the DSP (digital signal processor)chip is designed by employing SMIC 0.18μm CMOS technology.Based on the CAN(controller area network)bus,stacked high-voltage-tolerant driving technology and floating substrate effects are applied to achieve a high-voltage-tolerant driver in the standard CMOS process,avoiding the cost of the high-voltage process.The port voltage is introduced to the output-driver-control module,decreasing the electrostatic discharge at the output.Furthermore,in this way the electrostatic protection circuit can be spared,thus saving the chip area.The tape-out outcomes indicate that the proposed structure meets the CAN bus communication requirements.And the result of the port ESD(electrostatic discharge)sensitivity test reaches Class-3B,which satisfies the application demands.关键词
