G562 Global Mixed-mode Technology Inc. Power Switch with Over-Voltage and UserProgrammable Current Limit Protection Features General Description The G562 is an integrated power switch with over-voltage and user-programmable current limit protection. The current limiting and thermal shutdown prevent failures caused by increasing power dissipation when continuous heavy loads or short circuit occurs. The current limit is user programmable. 200 mΩ High-Side MOSFET User-Programmable Current Limit Build-in Thermal Shutdown VIN range up to 30V Fast Over-Voltage Lockout (<1us) Battery Over-Voltage Lockout Under-Voltage Lockout Logic Level Enable Pin Protection Status Flag Output TDFN2X2-8 Package It disconnect power from output rapidly if over voltage is detected. In the case of an overcurrent condition, it limits the system current at the threshold value, and if the over current persists, switches the pass element OFF after a blanking period. A built-in charge pump is used to drive the N-channel MOSFET. Applications High-Side Power Protection Switch USB Power Management USB Host and Self-Powered Bubs USB Bus-Powered Hubs Hot Plug-In Power Supplies Battery-Charger Circuits Other features include under-voltage lockout, battery over-voltage lockout, and fault FLAG output that indicate fault events. The G562 is available in TDFN2X2-8 Package. Ordering Information ORDER NUMBER MARKING OV THRESHOLD TEMP.
