Maximum Charge Time Selectable Top-Off Mode for Achieving Dependingon the chemistry, the bq2000T providesa
Maximum Capacityin NiMH Batteries numberof charge termination criteria: Rateof temperature rise (ΔT/Δt) (for NiCd and
• Programmable Trickle-Charge Mode forNiMH)
Reviving Deeply Discharged Batteries and for Minimum charge current (for Li-Ion)
Postcharge Maintenance Maximum temperature
• Built-in Battery Removal and Maximum charge time
Detection Sleep Mode for Low Power Consumption safety, the bq2000T inhibits fast charge until the voltage and temperature are within
APPLICATIONS limits.If the battery voltageis below the threshold, the bq2000T uses
• Multi-Chemistry Charger to condition the battery. For NiMH
• Nickel Charger the bq2000T provides an optional top-off
• High-Power, Multi-Cell Chargerto maximize the battery capacity.
The integrated high-speed comparator allows the
bq2000T to be the basis for a complete,
high-efficiency battery charger circuit for both
nickel-based and lithium-based chemistries.
