DESCRIPTION (continued)
In addition to the standard features, the bq24901 offers battery temperature monitoring and status display. The
temperature-sense circuit continuously measures battery temperature using an external thermistor and
suspends charge until the battery temperature is within the user
–
defined thresholds. The STAT pins indicate
conditions of operation of the charger. These outputs can be used to drive an LED or interface to a host
microcontroller.
These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
