of four input resistors to Op Amp OP1. The feedback
resistors remain constant. This ratio of input to feedback
resistors determines the gain. Putting external resistors
in series with the inputs reduces the gain of the amplifier.

are read at AO with respect to a DC
bias voltage of 2.5V. Therefore, the voltage range of
VCS

and VCS

changes depending upon the
direction of current flow (i.e. battery cells are in Charge
or Discharge—Table 21).

By calculating the difference of VCS
12
and VCS
21
the
offset voltage of the internal op-amp circuitry is
cancelled. This allows for the accurate calculation of
current flow into and out of the battery cells.
Pack current is calculated using the following formula:
VOLTAGE REGULATOR
The X3100 and X3101 are able to supply peripheral
devices with a regulated 5VDC±0.5% output at pin
RGO. The voltage regulator should be configured
externally as shown in Figure 10.
The non-inverting input of OP1 is fed with a high
precision 5VDC supply. The voltage at the output of the
voltage regulator (V
RGO
) is compared to this 5V
reference via the inverting input of OP1. The output of
OP1 in turn drives the regulator pnp transistor (Q1). The
negative feedback at the regulator output maintains the
voltage at 5VDC±0.5% (including ripple) despite
changes in load, and differences in regulator transistors.
When power is applied to pin VCC of the X3100 or
X3101, V
RGO
is regulated to 5VDC±10% for a nominal
time of T
OC
+2ms. During this time period, V
RGO
is
“tuned” to attain a final value of 5VDC±0.5% (Figure 2).
The maximum current that can flow from the voltage
regulator (I
LMT
) is controlled by the current limiting
resistor (R
LMT
) connected between RGP and VCC. When
the voltage across VCC and RGP reaches a nominal
2.5V (i.e. the threshold voltage for the FET), Q2 switches
ON, shorting VCC to the base of Q1. Since the base
voltage of Q1 is now higher than the emitter voltage, Q1
switches OFF, and hence the supply current goes to zero.
Typical values for R
LMT
and I
LMT
are shown in Table 27.
In order to protect the voltage regulator circuitry from
damage in case of a short-circuit, R
LMT
≥
10
should
always be used.

When choosing the value of R
LMT
, the drive limitations
of the PNP transistor used should also be taken into
consideration. The transistor should have a gain of at
least 100 to support an output current of 250mA.

4KBIT EEPROM MEMORY
The X3100 and X3101 contain a CMOS 4k-bit serial
EEPROM, internally organized as 512 x 8 bits. This
memory is accessible via the SPI port, and features the
IDLock function.
The 4kbit EEPROM array can be accessed by the SPI
port at any time, even during a protection mode, except
during sleep mode. After power is applied to VCC of the
X3100 or X3101, EEREAD and EEWRITE Instructions
