Note 1: If SWEN = 0 and VCELL < VCE, then OVP/LMON stays high and charging is prohibited.

VSS
VCC
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.
Note 3: UVP/OCP stays high until the microcontroller writes a “1” to the UVPC bit in the control register. This sets the signal low, which turns on the
discharge FET. The FET cannot be turned on prior to this time.

Table 22. Over-discharge Protection Mode—Event Diagram Description
Event
Event Description
[0,1)
— Charge FET is ON (OVP/LMON = VSS)
— Discharge FET is ON (UVP/OCP = VSS), and hence battery cells are permitted to discharge.
— All cell voltages (VCELL1 - VCELL4) are above the Over-discharge threshold voltage (VUV).
— 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 (VCELL), falls below VUV.
— The internal over-discharge detection delay timer begins counting down.
— The device is still in normal operation mode
(1,2)
The internal over-discharge detection delay timer continues counting for TUV seconds.
[2]
— The internal over-discharge detection delay timer times out, AND VCELL is still below VUV.
— The internal over-discharge sense circuitry switches the discharge FET OFF (UVP/OCP = Vcc).
— The charge FET is switched OFF (OVP/LMON = VCC).
— The device has now entered over-discharge protection mode.
— At the same time, the device enters sleep mode (See section “Voltage Regulator” on page 22).
(2,3)
While device is in sleep (in over-discharge protection) mode:
— The power to ALL internal circuits is switched OFF limiting power consumption to less than 1A.
— The output of the 5VDC voltage regulator (RGO) is 0V.
— Access to the X3100/X3101 via the SPI port is NOT possible.
