Description
The bq2014H NiCd/NiMH Gas Gauge IC is intended for batterypack or in-system installation to maintain an accurate record of available battery capacity.
Features
- Accurate measurement of available capacity in NiCd or NiMH batteries.
- Low-cost battery management so-
lution for pack integration
- As
little
as
1 2
square
inch
of
PCB for complete circuit
- Low operating current (120µA
typical)
- Less than 100nA of data
retention current.
- High-speed (5kb/s) single-wire communication interface (HDQ bus) for critical battery parameters.
