Modern electrical systems are reliant on many different components and peripherals that run off of a power source or need a regulated or efficient power delivery. Battery Charger controllers are one of the components used to ensure an efficient and cost effective power delivery to the battery or other load. The LTC4085EDE#PBF is an example of a PMIC (Power Management Integrated Circuit) charger controller providing a regulated power input to the battery from a wall adapter or USB port. It has a high efficiency power step-down regulator, reverse current protection, and autonomously selects the battery operating mode.

The LTC4085EDE#PBF is designed to be used with a Li-ion battery or Lead acid cell with 5 Cells in Series. It can support a constant voltage/constant current charger profile with a selectable float voltage between 4.0V and 4.5V. The charging current is adjustable up to a maximum of 1.3A with 0.5A accuracy. The device supports multiple protection features like overcharging, reverse current protection, thermal protection, and overvoltage protection. In addition, the LTC4085EDE#PBF offers four fully autonomous modes that can be selected by a single input pin.

The first mode is battery charging where the wall adapter or USB port is checked for an input voltage. If sufficient voltage is available, the controller steps down the power and charges the battery. Current is regulated automatically via a current sense resistor in order to protect the battery from being overcharged. If a charger is not present, the controller will switch to a low power mode.)

The second mode is short circuit protection. If a short circuit is detected on the power input, the controller immediately stops charging the battery. This prevents damage to the device or battery. The device will then reset and revert to battery charging mode when the power input is restored.

The third mode is overvoltage protection. If the input voltage exceeds the maximum allowed, the controller will shut down the battery charging process and switch to a low power mode. When the input voltage returns to normal, the device will automatically resume charging.

The fourth mode is thermal regulation. The controller has an onboard thermal sensor which monitors device temperature and shuts down the charging process if a certain temperature is exceeded. This protects the device from overheating and damaging the battery.

The LTC4085EDE#PBF is a highly integrated battery charger controller, providing a simple and cost-effective solution to the power delivery needs of portable devices and robotics. The device is ideal for use in applications such as laptops, cell phones and tablets, and robotic applications where an efficient and reliable power source is required.
