FEATURES  
DESCRIPTION

•
Monitors up to Two Individual Cell Voltages  
and Temperatures  
The bq76PL102 PowerLAN dual-cell battery monitor  
is part of a complete scalable battery management  
system for use with arrays of up to 12 Li-Ion  
rechargeable cells. The bq76PL102 connects to one  
or two cells in a series string, performs voltage and  
temperature monitoring of each individual cell, and  
reports these parameters over the PowerLAN  
communication network. Together with a bq78PL114  
master-gateway battery controller, the bq76PL102  
•
Part of a Complete Low-Cost Solution for  
Battery Packs of up to 12 Series and One or  
More Parallel Cells (When Used With  
bq78PL114).

a
complete battery  
system for  
monitoring and  
higher cell-count  
PowerPump™ Cell Balancing Transfers  
Charge From Cell to Cell During all Operating  
Conditions – No Wasteful Current Bleeding or  
Associated Heat Buildup.  
Partitioning of the battery monitor function on a per  
cell basis permits connection and measurement close  
to the cell. This results in superior accuracy and  
management over competing solutions. This scheme  
also facilitates the PowerPump cell balancing system,  
a technique which actively balances capacities of  
Li-Ion batteries without the excessive heat or  
limitations of bleed-balancing techniques.  
Unique PowerLAN™ Isolated Communications  
Technology Permits Simultaneous  
Measurement of All Individual Cell Voltages in  
a Series String.  
Low Current Consumption:

<250 µA Active  
The bq76PL102 PowerPump cell balancing  
<35 µA Standby  
technology uses  
a charge-transfer methodology  
which does not bleed off excess energy as heat, but  
instead moves energy dynamically from cell to cell as  
needed. Balancing is performed during all battery  
operational modes – charge, discharge, and rest.  
Balancing is automatically coordinated between all  
cells on a PowerLAN system. PowerPump balancing  
technology results in longer run time and longer cell  
life.

Internal LDO Regulator for Support Circuitry  
Ultrasmall Footprint, 3-mm × 3-mm  
Millivolt Measurement Resolution Using  
Delta-Sigma A/D Converter  
The PowerLAN communications architecture has  
been engineered to provide robust communications in  
tough EMI/RFI environments while avoiding the  
excessive power draw, high parts count, and elevated  
cost of other solutions. PowerLAN permits easy  
scalability using series connections of bq76PL102  
dual-cell battery monitors. High-cell-count battery  
systems of up to 12 series cells are easily  
constructed without complicated high-voltage cell  
measurement restrictions.

Self-Calibrating Time Base – No Crystal  
Required When Used With bq78PL114  
APPLICATIONS  
•
•
•
•
Uninterruptible Power Supplies (UPS)  
Portable Medical and Test Equipment  
Electric Bikes and Mild-EV Battery Packs  
Multicell Series Strings ≥ 5S  
The bq76PL102 works with the bq78PL114  
master-gateway battery controller.
