T63H0008A
under the overcharge detection voltage by the internal impedance, the T63H0008A release the overcharge
condition.
Note:(1).If the battery is charged to a voltage higher than the overcharge detection voltage (VDET1) and the battery voltage does
not fall below the overcharge detection voltage (VDET1) even when a heavy load is connected, the detection of
over-current 1 , over-current 2 and load short-circuiting does not work .Since an actual battery has the internal
impedance of several dozens of mW, the battery voltage drops immediately after a heavy loadwhich causes
over-current is connected, and the detection of over-current 1, over-current 2 and load short -circuiting then works..
(2).When a charger is connected after the overcharge detection, the overcharge condition is not released even if the battery
voltage is below the overcharge detection voltage VDET1. The overcharge condition is released when the V- pin
voltage goes over the charger detection voltage VDET 5 by removing the charger.
Over-discharge condition
www.DataSheet4U.com When the battery voltage falls below the over-discharge detection voltage (VDET2) during discharging
under the normal condition and the detection continues for the over-discharge detection delay time
(tVDET2) or longer, the T63H0008A turns the discharging control FET off to stop discharging. This
condition is called the over-discharge condition. When the discharging control FET turns off, the V- pin
voltage is pulled up by the RV-D resistor between V- and VDD in the IC. The voltage difference between
V- and VDD then falls bellow 1.3V (typ.), the current consumption is reduced to the power-down current
consumption (ISB). This condition is called the power -down condition.The power -down condition is
released when a charger is connected and the voltage differencebetween V- and VDD becomes 1.3 V (typ.)
or higher. Moreover when the battery voltage becomes the over-discharge detection voltage or higher, the
T63H0008A turns the discharging FET on and returns to the normal condition.
Charger detection
When a battery in the over-discharge condition is connected to a charger and provided that the V- pin
voltage is lower than the charger detection voltage (VDET 5), the T63H0008A releases the over-discharge
condition and turns the discharging control FET on as the battery voltage becomes equal to or higher than
the over-discharge detection voltage (VDET2) since the charger detection function works. This action is
called charger detection.
When a battery in the over-discharge condition is connected to a charger and provided that the V- pin
voltage is not lower than the charger detection voltage (VDET5), the T63H0008A releases the
over-discharge condition when the battery voltage reaches the over-discharge detection voltage (VDET2) +
over-discharge hysteresis (VHDT2 ) or higher.
Abnormal charge current detection
If the V- pin voltage falls below the charger detection voltage (VDET 5) during charging under normal
condition and it continues for the overcharge detection delay time (t VDET1) or longer, the chargingcontrol
FET turns off and charging stops. This action is called the abnormal charge current detection. Abnormal
charge current detection works when the DOUT pin voltage is “H” and the V- pin voltage falls below the
charger detection voltage (VDET 5). Consequently, if an abnormal charge current flows to an
over-discharged battery, the T63H0008A turns the charging control FET off and stops charging after the
battery voltage becomes higher than the over-discharge detection voltage which make the DOUT pin
