ISL6295
Low Voltage Fuel Gauge
The ISL6295 is a cost-effective, highly accurate IC that
measures, stores, and reports all of the critical parameters
required for rechargeable battery monitoring with a minimum
of external components. It precisely measures charge/
discharge current as well as voltage and temperature of a
battery pack. In addition, the ISL6295 accurately
accumulates both charge and discharge current as
independent parameters. Temperature history can also be
maintained for calculating self-discharge effects.
The ISL6295 integrates a highly accurate 16-bit (15-bit plus
sign) integrating A/D converter that performs calibrated
current measurement to within ±0.5% error. On-chip
counters precisely track battery charge/discharge and
temperature history. Also included are an on-chip voltage
regulation circuit, non-crystal time base, and on-chip
temperature sensor. The operating voltage range of the
ISL6295 is optimized to allow a direct interface to a single
cell Li-Ion/Li-Poly pack. 256 bytes of general-purpose
nonvolatile EEPROM storage are provided to store factory
programmed, measured, and user defined parameters.
Efficient communication is provided through an industry
standard SMBus/I
2
C compatible 2-wire communications
interface. This interface allows the host to determine
accurate battery status for effective system power
management and for communication to the end user. A
battery management solution utilizing the ISL6295 delivers
both space and total system component cost savings for a
wide variety of battery operated applications.
Features
Measures, maintains, and reports all critical rechargeable
battery parameters with high accuracy
Supports Lithium Ion and Lithium Polymer battery packs
Current measurement with 16-bit (15-bit plus sign)
integrating A/D accurate to less than ±0.5% error
Calibrated temperature measurement accurate to within
±3
°
C absolute using on-chip temp sensor or external
thermistor
Accumulation of charge current, discharge current,
temperature, and voltage in independent 32-bit registers
256-byte nonvolatile EEPROM stores factory
programmed, measured, and user-defined parameters
In-system offset calibration compensates for offset error in
current measurement
Industry standard SMBus/I

C compatible 2-wire
communications interface
- SMBus V1.1 with PEC/CRC-8 communication
-20°C to +85°C operating temperature range
NTC pin can be configured as a thermistor input or GPIO
GPAD pin can be configured as an independent A/D input
or GPIO
Flexible power operating modes allow low-power
monitoring of battery conditions during system full
operating and standby conditions:
- Run: Continuous Conversion; 85μA typ.
- Sample: Sample interval from 0.5-64s @ 45μA typ.
- Sample-Sleep: Sample interval from 0.5-138s min. @
20μA typ.
Shelf-Sleep mode reduces power consumption to pack
storage conditions to 300nA typ., with automatic wake-up
upon pack insertion.
