The nPM Fuel Gauge Board is a plug-and-play extension board for the nPM1300 Evaluation Kit (EK). The board is designed for the battery discharge and data collection needed for battery modeling without the need for expensive measurement equipment or specialized expertise. When used with the nPM1300 EK, the board facilitates the profiling and generation of battery models for Li-ion, Lithium-polymer (Li-Poly), and Lithium iron phosphate (LiFePO4) batteries in the nPM PowerUP computer application.
The nPM Fuel Gauge Board supports batteries with capacities ranging from 100 mAh to 3000 mAh across the battery's operating voltage and temperature range.
Key features
- Constant-current sink circuit for battery profiling
- Status indicator LEDs
- Connection headers compatible with the nPM1300 EK
