battery is fully charged the current into the battery
has not to be more than C/25 (Nimh battery). In
order to perform finely this, the CMD-PWM pin
must be driven with PWM function (in the same
time, the CMD-MODE must be kept low). The duty
cycle allows to adjust the mean current needed.
CHARGE MODE
The CMD-MODE pin, when high (and CMD-PWM
low), handles the switch in charge mode. This
switch allows the battery charge with a strong
current. The drop of this internal P-Channel MOS
is very low (200mV @ 800mA) in order to optimize
the efficiency of the charge.
The switch is not internally protected against short
circuit or overcurrent condition.
When the switch is ON (CMD-MODE high and
CMD-PWM low), the current direction into the chip
is from V
CHARGE
to V
BATT
. The reverse current
when the switch is ON must be null; this is
obtained by mean of an internal circuitry that
switch OFF the internal P-MOS when the V
BATT
is
higher than V
CHARGE
, whatever the status of the
CMD-MODE. When the CMD-MODE pin is low or
in high impedance the switch is OFF, while it is ON
when the signal on that pin is high.
REVERSE MODE
When
the
CDM-REVERSE pin, the switch allows to supply
the accessories with a strong current. The drop of
the internal P-Channel MOS is very low (200mV
@ 800mA) and the switch properly work for V
BATT
higher than 2.5V. This allows to supply energy on
the V
CHARGE
pin. When the switch is ON
(CMD-REVERSE high) the current direction into
the chip is from V
BATT
to V
CHARGE
.
The reverse current (from V
CHARGE
to V
BATT
)
when the switch is ON must be null; this is
obtained by mean of an internal circuitry that
switch
OFF
the
internal
V
CHARGE
is higher than V

status of the CMD-REVERSE. When the level of
CMD-REVERSE pin is low or in high impedance,
the switch is OFF, while it is ON when the signal
on CMD-REVERSE pin is high.

OVERVOLTAGE PROTECTION
This function allows to held the switches OFF
when the voltage level on V
BATT
is higher than a
maximum voltage whatever are the values of
CMD-PWM, CMD-MODE and CMD-REVERSE.
This maximum voltage is shown in the electrical
characteristic (typical threshold 5.7V). From the
moment in which the o.v.protection is activated, it
will be possible to turn ON again the switch only
when the V
CHARGE
value decreases down to 2.5V
typically, it doesn't matter which operation mode is
selected. The protection works only when the
battery is in charge or precharge mode, i.e.
V
CHARGE
> V
BATT
.
This represents, in fact, the typical application
condition where the battery could increase its
value, i.e. When charge or precharge mode are
used.
CHARGER DETECTION MODE
This function allows to generate a digital signal
(CHARGER-OK) to indicate if the V
CHARGE
voltage is higher than 2.5V and the reverse
function is inactive. This functionality allows to
determine if the charger is present or not; if the
V
CHARGE
is
lower
CHARGER-OK goes into high impedance (open
drain). When the reverse function is active, this
open drain have the V

information.

THERMAL PROTECTION
An internal thermal shutdown circuitry will switch
OFF the P_MOS, only in precharge or in charge
mode, when the junction temperature reaches
typically 180°C. This has been implemented in
order to protect the device from overburning. 20°C
