DESCRIPTION
The 74LV4799 is a low-voltage Si-gate CMOS control IC for battery management. It consists of:
? 17-stage divider
? 10-stage up/down counter
? Control logic
? Integrated precision oscillator (using external timing components)
? Automatic power-ON reset
? Scan test facilities
? Battery charging/full indication output (LED)
? Battery-low indication output (MOLLI)
? Open-drain-N outputs for driving the load transistor
FEATURES
? Wide supply voltage range of 0.9 V to 6 V allows 1 to 4-cell
applications
? 10 V allowed on special inputs
? Supports virtually all battery chargers, including switched-mode
power supplies
? On-chip timer calculates the actual capacity of the battery by
measuring the charger time, discharge time and self-discharge time
? Automatic switch-over to trickle charge after completion of the
charge time
? Can be adjusted for use with different types of batteries:
– Charge time: 4 to 16 hours
– Discharge time: 15 minutes to 4.7 hours
– Self-discharge time: 50 to 100 days
? Battery status indication included:
– LED output for charging/full indication
– MOLLI output for battery-low indication
? LED mode select allows two different methods of indication
? Automatic power-ON reset
? Low-power consumption
? Requires only a few peripheral components
? Very accurate on-chip oscillator
? Scan test facilities included
? ICC category: non-standard.
APPLICATIONS
? Time-controlled NiCd and NiMH low-current chargers
? Domestic appliances such as rechargeable battery shavers,
electric toothbrushes etc.
? Portable equipment such as notebook PCs, laptop PCs, camera
flash units etc.
? Personal communications like cordless telephones, personal
mobile radios, pagers, etc.
