Overview
The BQ2003PNG4 is a battery management integrated circuit designed for the fast-charge and conditioning of nickel-cadmium or nickel-metal hydride batteries. It utilizes hysteretic PWM switch-mode control to manage charging cycles efficiently. The device features a push-pull output capable of controlling an external transistor to discharge the battery prior to charging, ensuring safety and optimal performance. It operates with a 5.0 V ±10% power input supply (VCC). The component is housed in a 16-pin DIP package.
Feature Summary
- Supports fast-charge and conditioning protocols for nickel-cadmium and nickel-metal hydride battery chemistries
- Employs hysteretic PWM switch-mode control architecture for efficient power regulation
- Includes a push-pull output stage to drive external transistors for pre-charge battery discharge
Applications
- Fast-charging systems for NiCd battery packs
- Conditioning circuits for NiMH battery arrays
- Battery management units requiring pre-discharge functionality
Procurement Notes
Verify the specific suffix 'G4' indicates lead-free and RoHS compliance status as per Texas Instruments documentation. Confirm the 16-pin DIP package type matches your PCB footprint requirements. Ensure the 5.0 V supply voltage aligns with your system design before procurement. Cross-reference the datasheet revision date to ensure compatibility with current manufacturing standards.
Selection Notes
Select this component when managing nickel-based battery chemistries requiring dedicated fast-charge and conditioning capabilities. The hysteretic PWM control offers a robust solution for these specific applications. Consider the 16-pin DIP package if through-hole mounting is required. Verify that the external transistor interface meets the system's discharge current requirements.
Part Context
The BQ2003 series from Texas Instruments focuses on battery management for rechargeable cells. The BQ2003PNG4 specifically targets nickel-cadmium and nickel-metal hydride technologies. It distinguishes itself through integrated hysteretic PWM control and pre-charge discharge capabilities, serving as a specialized controller within broader power management IC portfolios.
Replacement Considerations
The BQ2003S is a related variant within the same family. Verify pinout compatibility and electrical specifications against the official datasheet before substitution. No other public substitute part numbers are confirmed.
