LTC4160EPDC#PBF - High Efficiency PowerPath Manager and Li-Ion/Polymer Battery Charger

The LTC4160EPDC#PBF is a sophisticated power management IC designed by Linear Technology, now part of Analog Devices, to cater to the demanding needs of portable electronic devices. This versatile component combines a high-efficiency PowerPath manager with a full-featured Li-Ion/Polymer battery charger, ensuring that your device operates seamlessly while managing power from multiple sources and maintaining the battery in optimal condition.

Key Features:

• PowerPath Control: The LTC4160EPDC#PBF intelligently manages the power flow between the input source, battery, and load. It ensures that the load is powered from the input source when available, while simultaneously charging the battery. When the input source is removed, the IC seamlessly transitions to battery power without interruption to the load.
• Efficient Battery Charging: Designed to charge single-cell Li-Ion/Polymer batteries, the product features programmable charge current up to 2A, which can be set via an external resistor. The IC uses a constant-current/constant-voltage algorithm with temperature monitoring for safe and efficient charging.
• Instant-On Operation: The LTC4160EPDC#PBF supports instant-on operation even with a depleted battery, ensuring that the system remains functional and can boot up from a very low battery voltage.
• Thermal Regulation: To protect the battery and the system, the IC incorporates thermal regulation that reduces the charge current in the event of an over-temperature condition.
• Low Profile: The LTC4160EPDC#PBF comes in a low-profile (0.75mm) 22-lead DFN package, making it suitable for space-constrained applications.

Applications:

The LTC4160EPDC#PBF is ideal for a wide range of portable devices where efficient power management and battery charging are critical. It is commonly used in handheld instruments, medical devices, USB-powered gadgets, and other battery-powered consumer electronics that require a reliable power source.

Reliability and Quality:

Linear Technology's commitment to high-quality and reliability is evident in the LTC4160EPDC#PBF. The product is designed to meet the rigorous standards required by portable device manufacturers, ensuring long-term performance and durability in various operating conditions.

In summary, the LTC4160EPDC#PBF from Linear Technology is an essential component for designers looking to create sophisticated power management systems in their portable devices, offering a blend of efficiency, versatility, and reliability.
