TIDA-00845, Two-Port Automotive USB-2.0 Hub With Short-to-Battery Protection Reference Design with the ability to withstand a short of up to 18V DC on both down-stream ports, as well as Level 4 IEC 61000-4-2 ESD protection, overcurrent conditions and shorts to ground. This protection is provided by an integrated protection device - the TPD3S714-Q1. With short-to-battery (STB) protection, short-circuit protection and a fixed current-limit load switch on both down-stream ports, the TUSB4020BI USB 2.0 hub is isolated and protected from overvoltage and overcurrent conditions. down-stream port 1 includes a STB test simulator for applying 18V DC and two TPD3S714-Q1s to protect both the hub and a peripheral for easily demonstrating USB STB protection functionality
