Overview
| Topology | Other Topology |
| Input voltage | 4-30 V |
| IC revision | A1 |
Description
This reference design demonstrates a cost-optimized onboard battery-charger solution for mid- or low-end vacuum robots, which has up to 1.5-A charging-current capability with a small layout area, providing ±3% charging-voltage accuracy and ±3% charging-current accuracy.The design enables a stable and smooth precharging to constant-current (CC) and constant-voltage (CV) charging profile and has been evaluated with a 4S2P li-ion battery pack.
Features
- Wide input voltage range support: 4 V to 30 V (1-s to 6-s li-ion battery-charger solution)
- Up to 1.5-A maximum charging current
- Pure hardware-configurable 3-stage charging with external circuits
- Precharging, constant current (CC), and constant voltage (CV)
- CC and CV
- Implement precharge stage with simple analog circuit
- Achieve smooth and stable CC-to-CV transition with internal compensation and simple control logic
Typical applications
- Vacuum robot / Humanoid / Cordless vacuum cleaner
