[7] Operation
R5402N101KD
VD1 / Over-charge Detector
The VD1 monitors VDD pin voltage during charge. When the VDD voltage crosses over-charge detector
threshold VDET1 (Typ. 4.250V), the VD1 can sense over-charge and the output of COUT pin becomes “L”
and stop charging by turning off the external Nch-MOSFET.
After detecting over-charge, when the voltage of VDD pin is equal or less than the released voltage
from over-charge (Typ. 4.050V), or when the VDD voltage is less than the over-charge detector
threshold, if the charger is removed and connect a load, VD1 is released, then the output level of COUT
becomes “H” and by turning on the external Nch-MOSFET, the battery charger is ready to work again.
When the Input level of VDD pin is equal or more than over-charge detector threshold, and while a
www.DataSheet4U.com charger is disconnected from the battery pack, if a load system is connected to the battery pack, the
output level of COUT pin is “L”. However, load current can be flown through a parasitic diode of an
external Nch-MOSFET. Then, when the voltage level of VDD pin becomes lower than over-charge
detector threshold, the output level of COUT pin becomes “H”.
Output delay time for over-charge detect and released over-charge is internally fixed respectively.
Although the VDD voltage goes up to a higher level than over-charge detector threshold within the
output delay time (Typ. 1s), VD1 would not work for detecting over-charge. If the action for VD1 to
release is done and the condition returns to the initial one within the output delay time (Typ.16ms), VD1
cannot be released.
A level shifter is built in a buffer driver for the COUT pin, because of this, the “L” level is equal to the
voltage level of V- pin.
The output type of COUT pin is CMOS type. (The Output level is between VDD and V-.)
VD2/Over-discharge Detector
The VD2 monitors a VDD pin voltage during discharge. When the VDD voltage crosses the
over-discharge detector threshold VDET2 (Typ. 2.50V) from a high level to a lower level than VDET2, the
VD2 senses over-discharge and stop discharge by turning off an external Nch-MOSFET.
To reset the VD2 with the DOUT pin level being “H” again after detecting over-discharge, if VDD voltage
is equal or less than over-charge detector threshold, a charge current flows through a parasitic diode of
the external Nch MOSFET. After that, when VDD voltage is more than over-discharge threshold, DOUT
pin becomes "H", and by tuning on the external Nch MOSFET, discharge is possible. In the case that a
charger is connected to the battery pack, and VDD level is more than over-discharge detector threshold,
the output level of DOUT becomes “H” immediately. Without connecting a charger, if VDD pin voltage is
equal or more than the released voltage from over-discharge (Typ.3.0V), the output level of DOUT
becomes “H”.
When a cell voltage is equal to 0V, connecting a charger to the battery pack makes COUT pin become
"H" and the system is allowable for charge while the voltage of the charger is more than the maximum
limit of the minimum operating voltage (Vst) for 0V charge.
An output delay for over-discharge detection is fixed internally. (Typ. 20ms) Although the voltage of
VDD becomes equal or less than over-discharge detector threshold and if it becomes higher than
over-discharge detector threshold within output delay time, over-discharge detector does not work.
Output delay time for release from over-discharge is also set internally. (Typ. 1.2ms)
After detecting over-discharge by VD2, supply current would decrease, (VDD=2.0V, Max. 2.0µA.)
because unnecessary circuits are halted and being standby.
The output type of DOUT pin is CMOS type and its output level is in between VDD and VSS.
