Battery Switch has Four Enable Inputs for Disconnecting a Li+ Battery from a Load in Portable Applications

Maxim Integrated Products has introduced the MAX14525 battery switch with four enable inputs. Optimized for disconnecting a lithium-ion battery from its load, this device features a low, 35milliohm (typ) Ron and an ultra-low, 0.8microamp (typ) quiescent supply current. The MAX14525 integrates all necessary components (a comparator, logic, MOSFET, etc.) and eliminates up to eight additional components with its four unique control inputs. Packaged in a tiny (2mm x 2mm) 8-pin TDFN, the MAX14525 is ideal for use in cell phones, PDAs, and other portable applications.
