Current-Limit Switches are programmable from 50-600 mA.
August 14, 2009 -
Housed in 1.4 x 1.8 mm UTQFN package, Models MAX4995A/MAX4995AL/MAX4995B/MAX4995C/MAX4995AF feature ±10% accurate current limit, protecting host devices against faulty load conditions. To handle overcurrent events, Models MAX4995A/MAX4995AL/MAX4995AF go into autoretry mode, while Model MAX4995B latches off switch, and Model MAX4995C places device in continuous current-limit mode. All devices provide reverse-current protection, which prevents current from being dumped back into source.

Industry's Smallest, High-Accuracy, 50mA to 600mA Programmable Current-Limit Switches
Tiny, high-accuracy current-limit switches are programmable from 50mA to 600mA.
SUNNYVALE, CA-May 6, 2009-Maxim Integrated Products (NASDAQ: MXIM) introduces the MAX4995A/MAX4995AL/MAX4995B/MAX4995C/MAX4995AF family of 1.4mm x 1.8mm, high-accuracy, programmable current-limit switches. Designed to protect host devices against faulty load conditions, these devices feature a ±10% accurate current limit that can be programmed with an external resistor from 50mA to 600mA for design flexibility. These devices are ideal for SDIO and other load-switching applications, and their ultra-low, 170µA (typ) quiescent current makes them particularly well suited for battery-powered applications.
Each device in the family handles overcurrent events differently. The MAX4995A/MAX4995AL/MAX4995AF go into an autoretry mode, the MAX4995B latches off the switch, and the MAX4995C places the device in a continuous current-limit mode. Additionally, all devices provide reverse-current protection, which prevents current from being dumped back into the source.
Packaged in a lead-free, 1.4mm x 1.8mm, 10-pin UTQFN, the MAX4995 family is fully specified over the extended (-40°C to +85°C) and automotive (-40°C to +125°C) temperature ranges. Prices start at $1.10 (1000-up, FOB USA).
