SMPS Chargers Features
- Fast-charge control based on switching buck converter with high-side battery-current sensing
- Configuration for fast charge of 1, 2, 3, or 4 Li-Ion cells
- Charge termination by maximum voltage, selectable minimum current, or maximum time-out
- Constant current (upto 1.25A) and constant voltage (up to 16.8V) provided by on-board switch-mode regulator
- Bicolor-LED display
- Direct connections for battery and thermistor
- Maximum charge time of 5 hours
General Description
Fast charge is preceded by a pre-charge qualification period.
Fast charge termination occurs on:
- Minimum current – Imax divided by 10, 15, or 20
- Maximum time-out
The charger can be reset and a new charge cycle started by applicaton of power to the board or replacement of
the battery. The board automatically initiates a recharge when the battery voltage drops to 3.85V per cell.
