TP5100 2A Li-Ion Battery Charger Module

This TP5100-based charger module delivers up to 2A for Li-Ion cells, supporting dual-cell 8.4V and single-cell 4.2V configurations. It operates from a 5V–15V input and uses a high-frequency switching regulation scheme for efficient charging.

Charge configurations: dual-cell up to 8.4V or single-cell up to 4.2V
Input voltage range: 5V–15V
Switching frequency: 400 kHz
No external anti-backflow Schottky diode required
LED indicators:
- Red LED – charging
- Blue LED – standby
- Flashing Red/Blue – battery capacitor present but no battery connected
Both LEDs off indicates very low or very high VIN, or high temperature shutdown
Battery temperature protection
Reverse connection protection
Short-circuit protection
Maximum junction temperature: 120°C
Operating temperature: -40°C to 85°C

Note: This module is designed for Li-Ion charging applications and may require proper thermal management in compact enclosures.
