MAX714

The MAX714 is designed as one kind of NiCd/NiMH battery fast-charge controller that can be used in portable consumer products such as portable stereos and cordless phones, or battery-powered equipment such as laptop, notebook, and palmtop computers and handy-terminals and cellular phones. And this MAX714 terminates fast charge by detecting zero voltage slope, while the MAX713 uses a negative voltage-slope detection scheme.

Features of the MAX714 are:(1)fast charge NiMH or NiCd Batteries; (2)voltage slope, temperature, and timer fast-charge cutoff; (3)charge 1 to 16 series cells; (4)supply battery's load while charging (linear mode); (5)fast charge from C/4 to 4C rate; (6)C/16 trickle-charge rate; (7)automatically switch from fast to trickle charge; (8)linear or switch-mode power control; (9)5A max drain on battery when not charging; (10)5V shunt regulator powers external logic.

The absolute maximum ratings of the MAX714 can be summarized as:(1)V+ to BATT-:-0.3V to +7V;(2)BATT- to GND:±1V;(3)BATT+ to BATT power not applied: +/-20 V;(4)BATT+ to BATT with power applied:the higher of ±20V or ±2V x (programmed cells);(5)DRV to GND:-0.3V to +20V;(6)lead temperature (soldering, 10sec):+300°C;(7)storage temperature range:-65°C to +150°C;(8)operating temperature ranges:0°C to +70°C;(9)REF current:10 mA.
