MAX1660 Datasheet (Maxim) - Digitally Controlled Fuel-Gauge Interface

MAX1660, Digitally Controlled Fuel-Gauge Interface

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 C
