Texas Instruments bq2002E/G Fast-Charge Management IC Datasheet
The bq2002E and bq2002G Fast-Charge ICs are low-cost CMOS battery-charge controllers designed for nickel cadmium and nickel-metal hydride battery applications. They control current-limited or constant-current supplies to serve as stand-alone or system-integrated chargers. The devices integrate fast charge with optional top-off and pulsed-trickle control in a single IC for charging one or more battery cells.

How can fast charge be inhibited?
Fast charge and top‑off can be inhibited by driving the INH pin high, which suspends the charge timer and LED status until the pin returns low.
What is the recommended supply voltage for the device?
The recommended supply voltage is 5.0 V, with a permissible range from 4.0 V to 6.0 V.
