3 Description
The BQ25172 is an integrated 800-mA linear charger
for 1-cell to 6-cell NiMH batteries targeted at industrial
and medical applications. The device has a single
power output that charges the battery. The system
load can be placed in parallel with the battery, as
long as the average system load does not prevent the
battery from being charged fully within the safety timer
duration. When the system load is placed in parallel
with the battery, the charge current is shared between
the system and the battery.
The device charges NiMH cells in constant current
mode only and terminates the charge cycle when
the programmable timer expires or the battery
voltage exceeds the VOUT_OVP threshold. In all
charge phases, an internal control loop monitors
the IC junction temperature and reduces the charge
current if an internal temperature threshold TREG, is
exceeded.
The charger power stage and charge current sense
functions are fully integrated. The charger function
has high accuracy current, charge status display, and
timer-based charge termination. The series cell-count,
charge current, and charge timer are programmable
through external resistors. Intermittent charging allows
a NiMH battery to automatically recharge for a
reduced timer duration once its voltage falls below the
recharge threshold.
