Functional Pin Descriptions
GPAD/IO1 (Pin 1)
General purpose A/D input or general purpose input/output
pin. Grounded if not used.
VP (Pin 2)
Cell input connection for the positive terminal of the Li-Ion
cell. Connects to the positive terminal of 1-cell series packs.
VP serves as the power supply input for the ISL6295.
SCL (Pin 3)

C data line connection
ROSC (Pin 5)
External bias resistor. 221k
(
±
0.1%) oscillator reference
setting resistor connected between this pin and GND.
NTC/IO0 (Pin 6)
Connection for an external temperature sensor using a
thermistor. Can also be configured as an open drain general
purpose input/output pin. Grounded if not used.
GND (Pin 7)
Analog and digital ground
SR (Pin 8)
Current measurement A/D input. Connects to the other
terminal of a grounded current sense resistor.
Theory of Operation
The ISL6295 contains a complete analog "front-end" for
battery monitoring as well as digital logic for control,
measurement accumulation, timing, and communications.
Major functions within the ISL6295 include:
Voltage Regulator
Precision Time Base
Temperature Sensor
256 Byte NV-EEPROM
32 Byte general purpose SRAM
Analog-to-Digital (A/D) Converter
32-bit Accumulators/Timers
SMBus/I
