1 / 8 page  SmartSwitch™ General Description The AAT4682 Dual Electronic Resettable fuse is part of the AnalogicTech Application Specific Power MOSFET (ASPM™) line of products. It has two 1A current limited P-channel MOSFET power devices that remain fully enhanced as long as the input power supply is above an under voltage lockout threshold, and the load is below the current limit setting. If the load increases above the current limit setting, as is the case during a short circuit, the MOSFET effectively becomes a constant current source equal to the current limit. If the current limit condition persists long enough to heat the MOSFET to an extreme temperature, both devices will ther- mal cycle off and on until the current limit condition is removed. Independent open drain FAULT flags signal an over current or over temperature condi- tion. Quiescent current typically is a low 10µA. The AAT4682 is available in a 6 pin SOT-23, spec- ified over a -40 to 85°C temperature range. Features • Dual P-Channel MOSFETS • 500mA steady state load current • 600mA minimum current limit trip point • Low quiescent current, typically 10µA. • Over temperature protection • Fast transient response: • < 1µs response to short circuit • 400m Ω typical R DS(ON) • Undervoltage Lockout • Temp range -40 to 85°C • FAULT flag with 2ms blanking • 6-pin SOT23 package Applications • USB ports • Peripheral ports • Desktop PCs • Cell phone ports AAT4682 Dual Electronic Resettable Switches Typical Application COUTA 1 µF IN CIN 1 µF FAULTA OUTA GND AAT4682 5 2 6 INPUT GND GND OUTA FAULTA FAULTB FAULTB OUTB 4 OUTB COUTB 1 µF 3 1 4682.2001.11.0.9 1 |
