DESCRIPTION

The bq2400x series ICs are advanced Li-Ion linear
charge management devices for highly integrated and
space-limited applications. They combine high-
accuracy current and voltage regulation; FET pass-
transistor and reverse-blocking Schottky; battery
conditioning, temperature, or input-power monitoring;
charge termination; charge-status indication; and
charge timer in a small package.
The bq2400x measures battery temperature using an
external thermistor. For safety reasons, the bq2400x
inhibits charge until the battery temperature is within the
user-defined thresholds. Alternatively, the user can
monitor the input voltage to qualify charge. The
bq2400x series then charge the battery in three phases:
preconditioning, constant current, and constant
voltage. If the battery voltage is below the internal
low-voltage threshold, the bq2400x uses low-current
precharge to condition the battery. A preconditioning
timer is provided for additional safety. Following pre-
conditioning, the bq2400x applies a constant-charge
current to the battery. An external sense-resistor sets
the magnitude of the current. The constant-current
phase is maintained until the battery reaches the
charge-regulation voltage. The bq2400x then
transitions to the constant voltage phase. The user can
configure the device for cells with either coke or
graphite anodes. The accuracy of the voltage regulation
is better than ±1% over the operating junction
temperature and supply voltage range.
Charge is terminated by maximum time or minimum
taper current detection
The bq2400x automatically restarts the charge if the
battery voltage falls below an internal recharge
threshold.
