PS700 Fuel Gauge
The primary safety circuit provides cell protection from
conditions of overcharge, overdischarge and over-
The module fuel gauge provides State-Of-Charge
(SOC) and battery status data in accordance with the
SMBus standards version 1.1. The PS700 monitors the
cell voltages, battery temperature and current to
determine SOC and battery status. The State-Of-
Charge calculations are compensated for cell self-
current. Analog ICs from Seiko measure individual cell
voltages and voltage across the discharge FET. These
values are compared against internal reference values
and the gates of two N-channel power MOSFETs are
controlled based on the comparison results.
