Current Sense Gain (CSG1, CSG0)

These bits set the gain of the current sense ampliﬁer.

These are x10, x25, x80 and x160. For more detail, see

section “Current Monitor Function” on page 20.

Table 14. Current Sense Gain Control

Charge/Discharge Control (OVPC, UVPC)

The OVPC and UVPC bits allow control of cell charge

and discharge externally, via the SPI port. These bits

control the OVP/LMON and UVP/OCP pins, which in turn

control the external power FETs.

Using P-channel power FETs ensures that the FET is

on when the pin voltage is low (Vss), and off when the

pin voltage is high (Vcc).

OVP/LMON and UVP/OCP can be controlled by using

the WCNTR Instruction to set bits OVPC and UVPC in

the Control register (See page 10).

Table 15. UVP/OVP Control

It is possible to set/change the values of OVPC and

UVPC during a protection mode. A change in the state

of the pins OVP/LMON and UVP/OCP, however, will not

take place until the device has returned from the

protection mode.

Cell Voltage Balance Control (CBC1-CBC4)

This function can be used to adjust individual battery

cell voltage during charging. Pins CB1–CB4 are used to

control external power switching devices. Cell voltage

balancing is achieved via the SPI port.

Table 16. CB1—CB4 Control

CB1–CB4 can be controlled by using the WCNTR In-

struction to set bits CBC1–CBC4 in the control register

(Table 16).

STATUS REGISTER

The status of the X3100 or X3101 can be veriﬁed by

using the RDSTAT command to read the contents of the

Status Register (Table 17).

Table 17. Status Register.

The function of each bit in the status register is shown

in Table 18.

Bit 0 of the status register (VRGS+OCDS) actually

indicates the status of two conditions of the X3100 or

X3101. Voltage

Regulator

Status

(VRGS)

is

an

internally generated signal which indicates that the

output of the Voltage Regulator (VRGO) has reached an

output of 5VDC ± 0.5%. In this case, the voltage

regulator is said to be “tuned”. Before the signal VRGS

goes low (i.e. before the voltage regulator is tuned), the

voltage at the output of the regulator is nominally 5VDC

± 10% (See section “Voltage Regulator” on page 21.)

Over-current Detection Status (OCDS) is another

internally generated signal which indicates whether or

not the X3100 or X3101 is in over-current protection

mode.

Signals VRGS and OCDS are logically OR’ed together

(VRGS+OCDS) and written to bit 0 of the status register

(See Table 18, Table 17 and Figure 2).
