Digital control reference design for cost-optimized battery test systems
Overview
| Topology | ADC |
| Input voltage | 9-14 V |
| Output 1 | 10 A |
| IC revision | E2 |
Description
This reference design provides a cost-effective solution for battery formation and test applications. This design uses the C2000™ real-time control MCU for high-resolution pulse-width modulation (PWM) generation, and constant-current (CC) and constant-voltage (CV)control loops. It efficiently utilizes the MCU, and does not require a precision digital-to-analog converter, which saves more than 30% in the bill of materials. The flexibility of current and voltage loops in software allows users to achieve multiple current and voltage levels output with one design.
Features
- Bidirectional current control up to 10 A with less than ±0.01% accuracy
- C2000 on-chip 12-bit ADC achieves control accuracy better than ±0.05%
- Parallel up to 8 channels for wide output current range
- Flexible digital constant-current and constant-voltage control loops
- Channel-to-channel crosstalk error below 0.01%
- Multilevel protection in hardware and software for reliable power supply design
Typical applications
- Industrial
- Battery test
