Typical perForMance characTerisTics
FAULT (Pin 1): Active-Low Fault Indicator Output. The
LTC4010 indicates various battery and internal fault condi-
tions by connecting this pin to GND. Refer to the Operation
and Applications Information sections for further details.
This output is capable of driving an LED and should be
left floating if not used. FAULT is an open-drain output to
GND with an operating voltage range of GND to V
CHRG (Pin 2): Active-Low Charge Indicator Output. The
LTC4010 indicates it is providing charge to the battery by
connecting this pin to GND. Refer to the Operation and
pin FuncTions

output is capable of driving an LED and should be left
floating if not used. CHRG is an open-drain output to GND
with an operating voltage range of GND to V
CHEM (Pin 3): Battery Chemistry Selection Input. This
pin should be wired to GND to select NiMH fast charge
termination parameters. If a voltage greater than 2.85V is
applied to this pin, or it is left floating, NiCd parameters
are used. Refer to the Applications Information section for
further details. Operating voltage range is GND to 3.3V.
