PIN DESCRIPTION
The descriptions of the pins are listed in Table 3-1.
TABLE 3-1:
PIN FUNCTION TABLES
3.1
Voltage Regulation Selection
(V
SET
)
MCP73861
: Connect to V
SS
for 4.1V regulation
voltage, connect to V
DD
for 4.2V regulation voltage.
MCP73862
: Connect to V
SS
for 8.2V regulation
voltage, connect to V
DD
for 8.4V regulation voltage.
3.2
Battery Management Input Supply
(V
DD2
, V
DD1
)
A supply voltage of [V
REG
(Typ) + 0.3V] to 12V is
recommended. Bypass to V
SS
with a minimum of
4.7 μF.
3.3
Battery Management 0V Reference
(V
SS1
, V
SS2
, V
SS3
)
Connect to negative terminal of battery and input
supply.
3.4
Current Regulation Set (PROG)
Preconditioning, fast and termination currents are
scaled by placing a resistor from PROG to V
SS
.
3.5
Cell Temperature Sensor Bias
(THREF)
Voltage reference to bias external thermistor for contin-
uous cell-temperature monitoring and pre-qualification.
3.6
Cell Temperature Sensor Input
(THERM)
Input for an external thermistor for continuous cell-
temperature monitoring and pre-qualification. Connect
to THREF/3 to disable temperature sensing.
3.7
All safety timers are scaled by C
TIMER
/0.1 μF.
3.8
Battery Charge Control Output
(V
BAT1
, V
BAT2
)
Connect to positive terminal of battery. Drain terminal
of internal P-channel MOSFET pass transistor. Bypass
to V
SS
with a minimum of 4.7
μ
F to ensure loop stability
when the battery is disconnected.
3.9
Battery Voltage Sense (V
BAT3
)
Voltage sense input. Connect to positive terminal of
battery. A precision internal resistor divider regulates
the final voltage on this pin to V
REG
.
3.10
Logic Enable (EN)
Timer Set
Input to force charge termination, initiate charge, clear
faults or disable automatic recharge.
3.11
Fault Status Output (STAT2)
Current-limited, open-drain drive for direct connection
to a LED for charge status indication. Alternatively, a
pull-up resistor can be applied for interfacing to a host
microcontroller.
3.12
Charge Status Output (STAT1)
Current limited, open-drain drive for direct connection
to an LED for charge status indication. Alternatively, a
pull-up resistor can be applied for interfacing to a host
microcontroller.
