DESCRIPTION

Impedance

Cell Temperature

The bq78PL114 master gateway battery controller is

part of a complete Li-Ion control, monitoring, and

safety solution designed for large series cell strings.

PowerPump Technology Transfers Charge

Efficiently From Cell to Cell During All

Operating Conditions, Resulting in Longer

Run Time and Cell Life

The bq78PL114 and bq78PL114S12 along with

bq76PL102 PowerLAN™ dual-cell monitors provide

complete battery-system control, communications,

and safety functions for a structure of three up to

twelve series cells. This PowerLAN system provides

simultaneous, synchronized voltage and current

measurements using one A/D per-cell technology.

–

bq78PL114S12 Adds User-Configurable

PowerPump Cell-Balancing Modes

•

High-Resolution 18-Bit Integrating Delta-Sigma

Coulomb Counter for Precise Charge-Flow

Measurements and Gas Gauging

This

eliminates

system-induced

noise

from

measurements and allows the precise, continuous,

real-time calculation of cell impedance under all

operating conditions, even during widely fluctuating

load conditions.

Multiple Independent Δ-Σ ADCs: One-per-Cell

Voltage, Plus Separate Temperature, Current,

and Safety

•

Simultaneous, Synchronous Measurement of

Pack Current and Individual Cell Voltages

PowerPump technology transfers charge between

cells to balance their voltage and capacity. Balancing

is possible during all battery modes: charge,

discharge, and rest. Highly efficient charge-transfer

circuitry nearly eliminates energy loss while providing

true real-time balance between cells, resulting in

longer run-time and improved cycle life.

Very Low Power Consumption

–

bq78PL114: < 250 µA Active, < 150 µA

Standby, < 40 µA Ship, and < 1 µA

Undervoltage Shutdown
