Description

The bq2158T provides a complete solution for the supervision of two series Li-Ion cells. Designed for battery pack integration, the bq2158T incorporates a bq2058T Pack Supervisor, two FETs, and all other components required to monitor overvoltage, undervoltage, and overcurrent conditions. The board provides direct connections for the negative and positive terminals of each cell. See Figure 1. Please refer to the bq2058T data sheet for specific information on the operation of thebq2058T.
