Texas Instruments bq2002D/T Fast-Charge Management IC Datasheet
The bq2002D/T Fast-Charge Management ICs are designed to provide reliable charge termination for nickel cadmium (NiCd) and nickel-metal hydride (NiMH) battery applications. These low-cost CMOS controllers can be used as the basis for a cost-effective stand-alone or system-integrated charger by controlling a current-limited or constant-current supply.

Questions answered in these manuals
How is fast charge terminated?
Fast charge terminates based on rate of temperature rise, maximum voltage, maximum temperature, or maximum time.
From: Texas Instruments bq2002D/T Fast-Charge Management IC Datasheet
How long does it take to sample a battery's temperature?
A single temperature sample is created by averaging 16 measurements taken over 18.18ms.

What is the function of the INH pin?
When high, the INH pin suspends fast charge in progress and resumes operation when returned low.

How is fast‑charge termination achieved?
Fast‑charge is terminated by any of four conditions: rate of temperature rise, maximum voltage, maximum temperature, or maximum time.

What does the INH pin do?
When high, the INH pin suspends fast‑charge, top‑off, and the internal charge timer; when low, normal operation resumes.
