电流限位开关, 2.7 V至5.5 V输入, TDFN-8
The is a single USB switch with autoreset and fault blanking in 8 pin TDFN package. This single current limited switch with autoreset supplies provides 500mA load in accordance with USB specifications. The MAX1946 operates from 2.7V to 5.5V input supply and consumes 40µA of quiescent current when operating and only 3µA in shutdown mode. An autoreset feature latches switch off in the event of short circuit which saves system power. The switch reactivates upon removal of shorted condition. The built-in thermal overload protection turns off switch when die temperature exceeds 160°C. Accurate internal current limiting circuitry protects input supply against both overload and short circuit conditions. An open-drain fault signal active-low FAULT notifies microprocessor µP when thermal overload, current-limit, undervoltage lockout UVLO or short circuit fault occurs. The fault blanking feature prevents fault signals from being issued when the device powers up the load.
