MAX4995A/AF/AL/ 50mA to 600mA Programmable MAX4995B/MAX4995C Current-Limit Switches General Description Features The MAX4995A/MAX4995AF/MAX4995AL/MAX4995B/ 50mA to 600mA Programmable Current Limit MAX4995C programmable current-limit switches feature 10% Accurate Current Limit internal current limiting to prevent damage to host devices Overload FLAG Threshold due to faulty load conditions. These analog switches fea- ture a low 130m (typ) on-resistance and operate from Low Dropout Voltage a +1.7V to +5.5V input voltage range. The current limit is Short-Circuit Protection adjustable from 50mA to 600mA, making these devices Thermal Shutdown ideal for SDIO (secure digital input/output) and other load- Reverse-Current Protection switching applications. 170A (typ) Supply Current Each device in the family handles an overcurrent event differently depending on the option selected. The +1.7V to +5.5V Supply Voltage Range MAX4995A/MAX4995AF/MAX4995AL go into an autoretry Tiny 10-Pin, 1.4mm x 1.8mm UTQFN Package mode, the MAX4995B latches off the switch, and the MAX4995C places the device in a continuous current-limit Applications mode. Additional safety features include thermal shutdown SDIO Ports Cell Phones to prevent overheating and reverse-current blocking to USB Ports MP3 Players prevent current from being driven back into the source. Notebook VGA Ports UTCA/ATCA Platforms The MAX4995A/MAX4995AF/MAX4995AL/MAX4995B/ GPS MAX4995C are available in a tiny 10-pin, 1.4mm x 1.8mm UTQFN, a 6-pin SOT23, or an 8-pin, 2mm x 2mm TDFN package and operate over the -40C to +125C extended Typical Operating Circuit appears at end of data sheet. temperature range.

Maximum power dissipation could be lower, limited by the thermal-shutdown protection included in this IC. Note 2: Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer board. For detailed information on package thermal considerations, refer to www.maximintegrated.com/thermal-tutorial. Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
