Maxim semiconductor introduces new chips for overvoltage protection .The MAX14529E/MAX14530E are overvoltage-protection devices with USB charger detection, low-dropout (LDO) regulator, and ESD protection.
When the input voltage exceeds the overvoltage threshold, the internal FET switch is turned off to prevent damage to the protected components.
The LDO output (LOUT) is powered from OUT and supplies 3.3V to the USB transceiver.
The charger detection detects a short between the USB D+ and D- data lines.
Main features of the MAX14529E/MAX14530E are : Input Voltage Protection Up to 28V , High-Current USB Charger Detection , 3.3V, 100mA LDO , Preset Overvoltage Protection Trip Level , Integrated Low RON 35mΩ (typ) FET Switch , Low-Capacitance USB High-Speed Data Line ESD , Thermal-Shutdown Protection .
