The LTC4160EUDC#PBF is an advanced battery charger controller, with integrated power path management from Linear Technologies. It is specifically designed for the battery charging of consumer, industrial and medical devices, using discrete semiconductor design with high efficiency, low power, and high reliability. The LTC4160EUDC#PBF utilizes a patented control architecture to enable fast, accurate and reliable charging to rechargeable batteries.

Application Field

The LTC4160EUDC#PBF is suitable for use in consumer electronics - laptops, tablet computers and PDAs, industrial battery charging, medical industrial charging and small standby generators. It has been designed to operate in a variety of conditions, and has an onboard power management controller that can provide up to 17 W of charging power with high output voltage and low losses in a wide temperature range of -20 to +70 °C.

Working Principle

The LTC4160EUDC#PBF operates as a part-time synchronous buck converter in discontinuous conduction mode (DCM), allowing operation at very low switching losses even for heavy loads. Its operating principle is based on using a high frequency power converter with a feedback loop for accurate regulation of the charging current and battery charge level.

The LTC4160EUDC#PBF can provide the necessary power for charging lithium-ion and other battery types, along with protecting the batteries from a variety of conditions. It has an on-board thermal protection, which shuts down the IC in order to avoid overheating and damage to the battery.

Additionally, the IC features an endpoint detection circuit, which detects the battery charge level and shuts off the converter when the battery reaches its targeted capacity. This enables the device to provide accurate and reliable charging and to maintain the battery health in a wide temperature range.

The LTC4160EUDC#PBF also includes thermal and current protection, which ensures safe and reliable operation of the device in the case of overload or excess temperature conditions. These features make the LTC4160EUDC#PBF a highly reliable device for the battery charging of various applications.
