, then OVP/LMON stays high and charging is prohibited.
Note 2:
OVP/LMON stays high until the microcontroller writes a “1” to the OVPC bit in the control register. This sets the signal low, which turns on the
charge FET. It cannot be turned on prior to this time.

Event
Event Description
[0,1)
—Charge FET is ON (OVP/LMON=V
SS
)
—Discharge FET is ON (UVP/OCP=V
SS
), and hence battery cells are permitted to discharge.
—All cell voltages (VCELL
1
-VCELL
4
) are above the Over-discharge threshold voltage (V
UV
).
—The device is in normal operation mode (i.e. not in a protection mode).
—The voltage of one or more of the battery cells (V
CELL
), falls below V
UV
.
—The internal over-discharge detection delay timer begins counting down.
—The device is still in normal operation mode
The internal over-discharge detection delay timer continues counting for T
UV
seconds.
—The internal over-discharge detection delay timer times out, AND V
CELL
is still below V
UV.
—The internal over-discharge sense circuitry switches the discharge FET OFF (UVP/OCP=Vcc).
—The charge FET is switched OFF (OVP/LMON=V
CC
).
—The device has now entered over-discharge protection mode.
—At the same time, the device enters sleep mode (See section “Voltage Regulator” on page 21).
