Battery Switch Features Four Enable Inputs for Disconnecting a Li+ Battery from a Load in Portable Applications
Note to Editor:
- The MAX14525 is a battery switch with four enable inputs optimized for disconnecting a lithium-ion battery from its load in portable applications.
- The MAX14525 integrates all requisite components (a comparator, logic, MOSFET, etc.) and eliminates up to eight additional components.
- The switch is packaged in a tiny, 2mm x 2mm TDFN package.
- Combining a small footprint with an ultra-low quiescent current, this IC is ideal for cell phones, PDAs, and other portable applications.

SUNNYVALE, CA—March 25, 2009—Maxim Integrated Products (NASDAQ: MXIM) introduces the MAX14525 battery switch with four enable inputs. Optimized for disconnecting a lithium-ion battery from its load, this device features a low, 35mΩ (typ) RON and an ultra-low, 0.8µA (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.
This switch is enabled from four possible inputs: a travel adapter input capable of high voltages up to 28V; an on-key input with a 3V ±2% 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°C to +85°C extended temperature range. Pricing starts at $1.10 (1000-up, FOB USA).
