Maxim DS2788E+

Part Number: DS2788E+

Descripción detallada

Manufacturer: Maxim

Description: IC, BATTERY FUEL GAUGE, TSSOP-14

Docket:
Rev 1; 6/08
Stand-Alone Fuel-Gauge IC with LED Display Drivers
General Description
The DS2788 measures voltage, temperature, and current, and estimates available capacity for rechargeable lithium-ion (Li+) and Li+ polymer batteries.

Cell characteristics and application parameters used in the calculations are stored in on-chip EEPROM. The available capacity registers report a conservative estimate of the amount of charge that can be removed given the current temperature, discharge rate, stored charge, and application parameters. Capacity estimation is reported in mAh remaining and percentage of full. LED display drivers and a debounced input make display of the capacity information easy. The LED pins can directly sink current, requiring only a resistor for setting the current in the LED display, thus reducing space and cost.
