MAX1660 Datasheet Digitally Controlled Fuel-gauge Interface

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 19-1308; Rev 1; 10/98 UAL IT MAN TION K A ET U E L H A S EV TA WS DA FOLLO Digitally Controlled Fuel-Gauge.

General Description

The MAX1660 digitally controlled fuel-gauge interface executes two essential functions for rechargeable battery-pack management: fuel gauging and pack overcurrent protection.

It accurately monitors a battery pack’s charge and discharge current flow, and records each using two independent, on-board Coulomb counters.

Each counter’s contents are externally accessible via a System Management Bus (SMBus™)-patible 2-wire serial interface.
