PIU
FAULT (Pin 1):
Active-Low Fault Indicator Output. The
LTC4010 indicates various battery and internal fault con-
ditions by connecting this pin to GND. Refer to the Opera-
tion 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
CC
.
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
Applications Information sections for further details. This
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
CC
.
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.
GND (Pin 4):
Ground. This pin provides a single-point
ground for internal references and other critical analog
circuits.
V
TEMP
(Pin 5):
Battery Temperature Input. An external
10k NTC thermistor may be connected between V
TEMP
and GND to provide temperature-based charge qualifica-
tion and additional fast charge termination control. Charg-
ing may also be paused by connecting the V
TEMP
pin to
GND. Refer to the Operation and Applications Informa-
tion sections for complete details on external thermistor
networks and charge control. If this pin is not used it
should be wired to INTV
DD
through 56k. Operating volt-
age range is GND to 3.3V.
V
CELL
(Pin 6):
Average Single-Cell Voltage Input. An
external voltage divider between BAT and V
CDIV
is attached
to this pin to monitor the average single-cell voltage of the
battery pack. The LTC4010 uses this information to pro-
tect against catastrophic battery overvoltage and to con-
trol the charging state. Refer to the Applications Information
section for further details on the external divider network.
Operating voltage range is GND to BAT.
V
CDIV
(Pin 7):
Average Cell Voltage Resistor Divider Ter-
mination. The LTC4010 connects this pin to GND provided
the charger is not in shutdown. V
CDIV
is an open-drain
output to GND with an operating voltage range of GND to
BAT.
TIMER (Pin 8):
Charge Timer Input. A resistor connected
between TIMER and GND programs charge cycle timing
limits. Refer to the Applications Information section for
complete details. Operating voltage range is GND to 1V.
SENSE (Pin 9):
Charge Current Sense Input. An external
resistor between this input and BAT is used to program
charge current. Refer to the Applications Information
section for complete details on programming charge
current. Operating voltage ranges from (BAT – 50mV) to
(BAT + 200mV).
BAT (Pin 10):
Battery Pack Connection. The LTC4010 uses
the voltage on this pin to control current sourced from V
CC
to the battery during charging. Allowable operating volt-
age range is GND to V
CC
.
INTV
DD
(Pin 11):
Internal 5V Regulator Output. This pin
provides a means of bypassing the internal 5V regulator
used to power the BGATE output driver. Typically, power
should not be drawn from this pin by the application
circuit. Refer to the Application Information section for
additional details.
BGATE (Pin 12):
External Synchronous N-channel MOSFET
Gate Control Output. This output provides gate drive to an
optional external NMOS power transistor switch used for
synchronous rectification to increase efficiency in the
step-down DC/DC converter. Operating voltage is GND to
INTV
DD
. BGATE should be left floating if not used.
PGND (Pin 13):
Power Ground. This pin provides a return
for switching currents generated by internal LTC4010
circuits. Externally, PGND and GND should be wired
together using a very low impedance connection. Refer to
PCB Layout Considerations in the Applications Informa-
tion section for additional grounding details.
