TEA1104 Battery Monitor and Fast Charge SMD IC for NiCd and NiMH Chargers

The TEA1104 is a Battery Monitor and Fast Charge IC designed specifically for NiCd (Nickel-Cadmium) and NiMH (Nickel-Metal Hydride) rechargeable battery charging applications. This SMD (Surface-Mounted Device) IC offers a complete solution for efficient battery management and fast charging in devices like power tools, cordless phones, and other consumer electronics. The TEA1104 features an integrated charge control system that optimizes the charging process for NiCd and NiMH batteries. It supports fast charging by monitoring battery voltage, temperature, and other parameters to ensure safe and efficient charging. The IC uses a constant current and constant voltage method to charge the battery, adjusting the current as needed to prevent overcharging or overheating. It is capable of detecting the battery’s charge state and can automatically switch to a trickle charge mode once the battery is fully charged. Additional features include over-voltage protection, temperature monitoring, and charge termination, ensuring that the battery is not damaged during the charging cycle. The TEA1104 IC also incorporates LED indicators to display the status of the battery during charging.
