Tool/software:
Hello,
I'm looking for guidance on selecting a Texas Instruments IC for a Ni-MH battery pack with a nominal 12V/3Ah rating, composed of 10 cells of 1.2V each (Ni-MH SC 3000mAh). Here are the primary requirements for the application:
-
Power Source and Charging Specs:
- I have a 15V/5A charger.
- The charging current for the battery pack is ideally within safe limits according to the standard charge/discharge specifications in the datasheet, with a nominal charge of 0.1C (300mA) and a fast charge of up to 1C (3A), though maintaining safe and efficient charging is essential.
-
Load Characteristics:
- The connected load consumes a steady 2.2A, and I need a solution that can reliably power the load while simultaneously charging the battery pack if needed.
-
Operational Requirements:
- The IC should support safe charging and discharging cycles for Ni-MH chemistry, ideally incorporating protections like temperature monitoring and cutoff voltage controls.
- I would like it to manage the charging and load power path automatically, prioritizing the load while ensuring that the battery is neither overcharged nor discharged below its safe cutoff of 1.0V per cell (10V total for the pack).
Could you recommend a suitable IC or set of components that can safely handle this simultaneous charge/load operation for Ni-MH batteries in this configuration? Additionally, advice on any external components or circuitry to manage thermal and overcharge protection would be greatly appreciated
