Standalone NiMH/NiCd fast charger fits in TSSOP-16 package

Linear Technology's LTC4010 is a complete NiMH/NiCd battery charger that requires no microcontroller or firmware programming. The IC includes charge initiation, monitoring, protection, charge termination, and constant-current control circuitry as it can fast charge 1- to 16-cell NiMH or NiCd batteries at rates up to 4A from a wide range of input supplies and wall adapter voltages from 5.5 to 34 V. The LTC4010 is suited for use in portable instruments, diagnostic and control systems, as well as back-up battery-management equipment.

The LTC4010's 550-kHz operating frequency enables the use of small inductors and capacitors, minimizing printed circuit board area. Other features include battery qualification, recharge, and top-off (for NiMH). Output signals are provided for indicating ready, end-of-charge, and fault status conditions. The part comes in a thermally enhanced 16-lead TSSOP package and is rated for operation from 0°C to 85°C. The 1000-piece pricing starts at $4.45 each.More information is available at www.linear.com.
