Linear Technology LTC4417GN - Priority PowerPath Controller

The LTC4417GN from Linear Technology is a sophisticated Priority PowerPath controller designed to ensure seamless transitions between multiple power sources in a system. This integrated circuit is housed in a compact SSOP-16 package, making it ideal for space-constrained applications where power supply reliability is critical.

Key Features:

• Triple PowerPath Inputs: The LTC4417GN can manage up to three power sources, automatically controlling which source is connected to the load based on priority and validity.
• Low Loss PowerPath Selection: It utilizes internal low-resistance MOSFETs to switch between power sources, minimizing conduction losses and maximizing efficiency.
• Priority-Based Selection: Users can set the priority sequence for the power sources, ensuring that the most critical source is used first when available.
• Wide Operating Voltage Range: The device operates over a wide voltage range from 2.5V to 36V, accommodating a variety of power sources such as batteries, wall adapters, and supercapacitors.
• Fast Switchover: The LTC4417GN provides fast and seamless transitions between power sources to ensure uninterrupted operation of the load.
• Adjustable Under-Voltage Lockout: Each input has an adjustable under-voltage lockout to disconnect a source that falls below a preset threshold, protecting the load from low-voltage conditions.
• Reverse Input Protection: The device includes reverse input protection to safeguard against incorrectly applied power supplies.

Applications:

The LTC4417GN is suitable for a wide range of applications where power supply redundancy and reliability are essential. These include:

• Portable and battery-powered devices
• Industrial and automotive systems
• Medical equipment
• Uninterruptible power supplies (UPS)
• Redundant power systems

With its robust power management capabilities, the LTC4417GN ensures that your critical systems remain operational even in the event of a power source failure. This makes it an invaluable component in any design that requires a fail-safe power supply solution.
