Table 24. Over-Current Protection Mode—Event Diagram Description
Event
Event Description
[0,1)
— Discharge FET is ON (OCP = Vss). Battery cells are permitted to discharge.
—VCS21 (VCS2 - VCS1) is less than the over-current threshold voltage (VOC).
— The device is in normal operation mode (i.e. not in a protection mode).
[1]
— Excessive current flows through the battery terminals P+, dropping the voltage. (See Figure 6.).
— The positive battery terminal voltage (P+) falls, and VCS21 exceeds VOC.
— The internal over-current detection delay timer begins counting down.
— The device is still in Normal Operation Mode
(1,2)
The internal Over-current detection delay timer continues counting for TOC seconds.
[2]
— The internal over-current detection delay timer times out, AND VCS21 is still above VOC.
— The internal over-current sense circuitry switches the discharge FET OFF (UVP/OCP = Vcc).
— The device now begins a load monitor state by passing a small test current (ILMON = 7.5A) out of pin
OVP/LMON. This senses if an over-current condition (i.e. if the load resistance < ROCR) still exists across
P+/P-.
— The device has now entered over-current protection mode.
— It is possible to change the status of UVPC and OVPC in the control register, although the status of pins
UVP/OCP and OVP/LMON will not change until the device has returned from over-current protection mode.
(2,3)
— The X3100/X3101 now continuously monitors the load resistance to detect whether or not an over-
current condition is still present across the battery terminals P+/P-.
