Hot Swap Controllers datasheet and documents for LTC4215IUFD-3#TRPBF
Hot Swap Controllers Overview
The LTC4215IUFD-3#TRPBF is a Hot Swap controller manufactured by Analog Devices Inc., designed for safe board insertion into live backplanes. It utilizes an external N-channel pass transistor to manage inrush current and supply voltage ramp rates. The device features an I2C interface with onboard ADC capabilities for monitoring load current, voltage, and fault status. Key electrical parameters include a wide operating voltage range of 2.9V to 15V and a 20μs circuit breaker filter for fast fault response. It operates within a temperature range of -40°C to +85°C and is housed in a 24-pin QFN package.
Hot Swap Controllers Feature Summary
- Enables safe insertion and removal from live backplanes using adjustable inrush current control
- Provides real-time monitoring of voltage and current via I2C compatible interface and onboard ADC
- Offers configurable fault handling with options for latch-off or automatic restart after overcurrent events
Hot Swap Controllers Applications
- Live board insertion systems
- Electronic circuit breakers
- Computer and server platform management
Hot Swap Controllers Procurement Notes
Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the manufacturer is Analog Devices Inc. Ensure the part number matches the exact thermal grade and pin configuration required for your PCB layout. Cross-reference the datasheet for the 24-pin QFN footprint dimensions to ensure mechanical compatibility.
Hot Swap Controllers Selection Notes
Select this component when precise I2C-based monitoring of power delivery is required alongside hot swap protection. The 20μs circuit breaker timeout suits applications needing rapid fault detection without excessive sensitivity to transient spikes. Consider the external N-channel MOSFET requirement for high-side drive implementation.
Hot Swap Controllers Part Context
This part belongs to the LTC4215 family of Hot Swap controllers. It shares core functionality with the LTC4215-2 but differs in circuit breaker timeout duration and default fault behavior. The IUFD designation specifies the industrial temperature range and QFN package type, distinguishing it from SSOP variants.
Hot Swap Controllers Replacement Considerations
LTC4215IUFD-3#PBF is a tube-packaged equivalent of the same functional device. For different fault handling characteristics, consider the LTC4215-2 series which offers extended circuit breaker filtering.
