The module fuel gauge provides State-Of-Charge
(SOC) and battery status data in accordance with the
SMBus standards version 1.1. The PS501 monitors the
cell voltages, battery temperature and current to deter-
mine SOC and battery status. The State-Of-Charge
calculations are compensated for cell self-discharge.
The remaining time calculation is compensated for
temperature and discharge rate. The parameters for
determining battery status flags and alarm thresholds
are all programmable, as is the battery design capacity
and the battery performance model data. Please refer
to the “PS501 Data Sheet” (DS21818) for details on
configuring the PS501 device.

FUNCTIONAL DESCRIPTION
PS501 Fuel Gauge
2.2
The primary safety circuit provides cell protection from
conditions of overcharge, overdischarge and over-
current. The analog safety IC measures individual cell
voltages, current and voltage across the safety FETs.
These values are compared against internal reference
values and the gates of two N-channel power
MOSFETs are controlled based on the comparison
results.
