DESCRIPTION
The DS2770 battery monitor and charge controller performs several functions needed for thorough battery maintenance. When used in conjunction with the host system’s processor, a battery-pack resident DS2770 may be utilized for applications that include charging, remaining capacity estimation, safety monitoring, and nonvolatile (NV) parametric storage.
FEATURES
■ Integrated charge controller supporting both rechargeable lithium and NiMH battery technologies
■ Available in two configurations:
– Internal 25mΩ current-sense resistor
– External user-selectable sense resistor
■ Current measurement:
– 15-bit bidirectional measurement
– Internal sense resistor configuration: 62.5μA LSB and ±2A dynamic range
– External sense resistor configuration: 1.56μV LSB and ±51.2mV dynamic range
■ Current accumulation
– Internal sense resistor: 0.25mAh LSB
– External sense resistor: 6.25μVh LSB
■ Voltage measurement with 4.88mV resolution
■ Temperature measurement using integrated sensor with 0.125°C resolution
■ 40 bytes of lockable EEPROM
■ 16 bytes of general-purpose SRAM
■ 42-day timer
■ Dallas 1-Wire® interface with 64-bit ID
■ 1.8V logic levels
■ Low power consumption:
– Active current: 80μA typical
– Sleep current: 0.5μA typical
