Linear Technology LTC4076EDD#TRPBF Battery Charger IC

The LTC4076EDD#TRPBF is a high-performance, standalone linear battery charger IC designed by Linear Technology, now part of Analog Devices, for charging single-cell lithium-ion batteries. This compact and efficient charging solution is ideal for portable electronic devices such as smartphones, digital cameras, and other USB-powered gadgets.

This charger IC is housed in a small 10-lead DFN package with a thermal pad to enhance heat dissipation, ensuring reliable operation even under high power conditions. The LTC4076EDD#TRPBF offers a programmable charge current up to 1.2A, allowing users to tailor the charging rate to the specific needs of their application and battery capacity.

One of the key features of the LTC4076EDD#TRPBF is its automatic recharge feature. Once the battery reaches the final float voltage, the charger terminates the charge cycle, but it will automatically restart charging if the battery voltage falls below a certain threshold. This ensures the battery remains fully charged without overcharging, which can extend the battery's lifespan.

The LTC4076EDD#TRPBF also includes a range of safety features to protect both the battery and the charger. These include thermal regulation, which reduces the charge current if the IC temperature rises to a preset threshold, and a timer termination function that ends the charge cycle after a predetermined period to prevent overcharging in case of an abnormal condition.

Additionally, this charger IC supports a wide input voltage range from 4.25V to 6.5V, making it compatible with various power sources. The device can be powered from a USB port or a wall adapter, providing flexibility in charging scenarios.

For design simplicity, the LTC4076EDD#TRPBF requires minimal external components, which can lead to a reduced board space and a simplified design process. This makes it an excellent choice for designers looking for a reliable, straightforward, and space-efficient charging solution for their lithium-ion battery-powered applications.

Overall, the LTC4076EDD#TRPBF by Linear Technology is a versatile and robust battery charger that offers high performance, multiple safety features, and design flexibility, making it a top choice for modern portable electronic devices.
