Table 20. Over-charge Protection Mode—Event Diagram Description
Event
Event Description
[0,1)
—Discharge FET is ON (UVP/OCP=V
SS
).
—Charge FET is ON (OVP/LMON=V
SS
), and hence battery cells are permitted to receive charge.
—All cell voltages (V
CELL
-V
CELL4
) are below the over-charge voltage threshold (V
OV
).
—The device is in normal operation mode (i.e. not in a protection mode).
[1]
—The voltage of one or more of the battery cells (V
CELL
), exceeds V
OV
.
—The internal over-charge detection delay timer begins counting down.
—The device is still in normal operation mode
The internal over-charge detection delay timer continues counting for T
OV
seconds.
The internal over-charge detection delay timer times out
(1,2)
[2]
AND
V
CELL
still exceeds V
OV.
—Therefore, the internal over-charge sense circuitry switches the charge FET OFF (OVP/LMON=Vcc).
—The device has now entered over-charge protection mode.
While in over-charge protection mode:
—The battery cells are permitted to discharge via the discharge FET, and diode D
2
across the charge FET
—The X3100 or X3101 monitors the voltages V
CELL1
-V
CELL4
to determine whether or not they have all fallen
below the “Return from over-charge threshold” (V
OVR
).
—(It is possible to change the status of UVP/OCP or OVP/LMON using the control register)
(2,3)
[3]
—All cell voltages fall below V
OVR
—The device is now in normal operation mode.
—The X3100/X3101 automatically switches charge FET=ON (OVP/LMON=Vss)
—The status of the discharge FET remains unaffected.
—Charging of the battery cells can now resume.
