Pin Descriptions
SNS
Current-sense input
Enables the bq2000T to sense the battery
current via the voltage developed on this pin
by an external sense-resistor connected in
series with the battery pack
V
SS
System Ground
LED
Charge-status output
Open-drain output that indicates the charg-
ing status by turning on, turning off, or
flashing an external LED
BAT
Battery-voltage input
Battery-voltage sense input. A simple resistive
divider, across the battery terminals, generates
thisinput.
TS
Temperature-sense input
Input for an external battery-temperature
monitoring circuit. An external resistive di-
vider network with a negative tempera-
ture-coefficient thermistor sets the lower
and upper temperature thresholds.
RC
Timer-program input
RC input used to program the maximum
charge-time, hold-off period, and trickle
rate during the charge cycle, and to disable
or enable top-off charge
V
CC
Supply-voltage input
MOD
Modulation-control output
Push-pull output that controls the charging
current to the battery. MOD switches high
to enable charging current to flow and low to
inhibit charging- current flow.
Functional Description
The bq2000T is a versatile, multi-chemistry battery-
charge control device. See Figure 1 for a functional block
diagram and Figure 2 for the state diagram.
