A battery switch with four enable inputs has been introduced by Maxim Integrated Products.
Optimized for disconnecting a lithium-ion battery from its load, the MAX14525 features a low, 35 milliohm (typ) Ron and an ultra-low, 0.8 microamp (typ) quiescent supply current. The MAX14525 integrates all necessary components (a comparator, logic, MOSFET) and eliminates up to eight additional components with its four unique control inputs. Packaged in a tiny (2 mm x 2 mm) 8-pin TDFN, the MAX14525 is ideal for use in cell phones, PDAs, and other portable applications.
The switch is enabled from four possible inputs: a travel adapter input capable of high voltages up to 28 V; an on-key input with a 3 V ±2 percent trigger threshold; a switch-enable input that is internally ANDed with the switched battery connection; and a factory-mode enable input.
The MAX14525 is fully specified over the -40 to +85 degrees Celsius extended temperature range.
