bq78PL114

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.

The bq78PL114 is completely user-configurable, with parametric tables in flash memory to suit a variety of cell

chemistries, operating conditions, safety controls, and data reporting needs. It is easily configured using the

supplied bqWizard™ graphical user interface (GUI). The device is fully programmed and requires no algorithm or

firmware development.
