PRINCIPLES OF OPERATION
The X3100 and X3101 provide two distinct levels of
functionality and battery cell protection:
First, in Normal mode, the device periodically checks
each cell for an over-charge and over-discharge state,
while continuously watching for a pack over-current
condition. A protection mode violation results from an
over-charge, over-discharge, or over-current state. The
thresholds for these states are selected by the user
through software. When one of these conditions occur, a
Discharge FET or a Charge FET or both FETs are
turned off to protect the battery pack. In an over-
discharge condition, the X3100 and X3101 devices go
into a low power sleep mode to conserve battery power.
During sleep, the voltage regulator turns off, removing
power from the microcontroller to further reduce pack
current.
Second, in Monitor mode, a microcontroller with A/D
converter measures battery cell voltage and pack current
via pin AO and the X3100 or X3101 on-board MUX. The
user can thus implement protection, charge/discharge,
cell balancing or gas gauge software algorithms to suit
the specific application and characteristics of the cells
used. While monitoring these voltages, all protection
circuits are on continuously.
In a typical application, the microcontroller is also
programmed to provide an SMBus interface along with
the Smart Battery System interface protocols. These
additions allow an X3100 or X3101 based module to
adhere to the latest industry battery pack standards.
PIN CONFIGURATION
PIN NAMES
PIN DESCRIPTIONS
Battery Cell Voltage (VCELL1-VCELL4):
These pins are used to monitor the voltage of each
battery cell internally. The voltage of an individual cell
can also be monitored externally at pin AO.
The X3100 monitors 4 battery cells. The X3101 monitors
3 battery cells. For the X3101 device connect the
VCELL4/VSS pin to ground.
