BATTERY VOLTAGE SENSE (V
BAT3
)
The MCP7386X monitors the battery voltage at the
V
BAT3
pin. This input is tied directly to the positive
terminal of the battery pack.
5.1.7
BATTERY CHARGE CONTROL
OUTPUT (V
BAT1
, V
BAT2
)
The battery charge control output is the drain terminal
of an internal P-channel MOSFET. The MCP7386X
provides constant current, constant voltage regulation
to the battery pack by controlling this MOSFET in the
linear region. The battery charge control output should
be connected to the positive terminal of the battery
pack.

Digital Circuitry
5.2.1
CHARGE STATUS OUTPUTS
(STAT1,STAT2)
Two status outputs provide information on the state of
charge. The current-limited, open-drain outputs can be
used to illuminate external LEDs. Optionally, a pull-up
resistor can be used on the output for communication
with a host microcontroller. Table 5-1 summarizes the
state of the status outputs during a charge cycle.
The flashing rate (1 Hz) is based off a timer capacitor
(C
TIMER
) of 0.1 μF. The rate will vary based on the
value of the timer capacitor.
During a FAULT condition, the STAT1 status output will
be off and the STAT2 status output will be on. To
recover from a FAULT condition, the input voltage must
be removed and then reapplied, or the enable input
(EN) must be de-asserted to a logic-low, then asserted
to a logic-high.
When the voltage on the THERM input is outside the
preset window, the charge cycle will not start, or will be
suspended. The charge cycle is not terminated and
recovery is automatic. The charge cycle will resume or
start once the THERM input is valid and all other qual-
ification parameters are met. During an invalid THERM
condition, the STAT1 status output will be off and the
STAT2 status output will flash.
5.2.2
The V
SET
input selects the regulated output voltage of
the MCP7386X. With V
SET
tied to V
SS
, the MCP73861
and MCP73862 regulate to 4.1V and 8.2V, respec-
tively. With V
SET
tied to V
DD
, the MCP73861 and
MCP73862 regulate to 4.2V and 8.4V, respectively.

5.2.3
LOGIC ENABLE (EN)
The logic enable input pin (EN) can be used to
terminate a charge at any time during the charge cycle,
as well as to initiate a charge cycle or initiate a recharge
cycle.
Applying a logic-high input signal to the EN pin, or tying
it to the input source, enables the device. Applying a
logic-low input signal disables the device and termi-
nates a charge cycle. When disabled, the device’s
supply current is reduced to 0.17 μA, typically.
