MAX1780 Advanced Smart Battery Pack Controller

Typical Operating Circuit

General Description

The MAX1780 Advanced Battery Pack Controller is a

smart battery pack supervisor that integrates a User

programmable Microcontroller Core, Coulomb-

Counter-based Fuel Gauge, a multi-channel Data

Acquisition Unit, a high-speed SPI Interface, and a

Master/Slave SMBus Interface. The 8-bit, RISC,

Microcontroller core is user programmable, and

provides battery pack designers with complete

flexibility in developing fuel gauging and control

algorithms. The Data Acquisition Unit can measure

individual cell voltages to within 50mV, total battery

stack voltage (up to 20.48V), and chip

internal/external temperature.

The user adjustable overcurrent comparators, along

with individual cell voltage measurements, allow the

MAX1780 to eliminate a separate primary pack

protection IC. The MAX1780 can be directly

connected to 2 to 4 series Lithium Ion cells, and

supplies itself through a fully integrated 3.4V low

drop out linear regulator.
