LTC1421CG-2.5概述

    Product Introduction
    The LTC1421/LTC1421-2.5 is a high-performance Hot Swap Controller specifically designed to ensure safe insertion and removal of printed circuit boards (PCBs) from live backplanes. It features robust capabilities for managing power transitions, protecting systems from potential faults, and offering programmable control of supply voltages. These controllers are ideal for applications requiring seamless operation in mission-critical environments, such as telecommunications, servers, storage systems, and industrial automation.
    Key Features:
    - Allows safe insertion and removal of boards from live backplanes.
    - Supports system reset and power-good status outputs.
    - Provides programmable electronic circuit breaker functionality.
    - Enables user-programmable supply voltage ramp-up rates.
    - Operates with supply voltages ranging from 3V to 12V.
    - Detects board insertion and removal via connection input pins.
    - Offers undervoltage lockout and power-on reset functionality.

    | Comparator Offset Voltage | ±10mV | - | ±10mV | mV |
    | Output Capacitor (CLOAD) | 0.047µF | - | - | µF |
    Notes:
    - Full operational temperature range: –40°C to 85°C.
    - Available in 24-pin SO and SSOP packages.
    Product Features and Advantages
    Unique Functionality:
    1. Safe Insertion/Removal: Ensures reliable board insertion/extraction without disrupting the live backplane, minimizing risk of damage.
    2. Electronic Circuit Breaker: Protects against shorts and excessive currents with programmable sensitivity.
    3. User-Controlled Voltage Ramp-Up: Enables smooth and gradual power delivery to downstream components.
    4. Advanced Reset Mechanism: Provides system reset in case of power failures, undershoots, or detected faults.
    5. Compact Form Factor: Suitable for space-constrained designs with small package sizes.
    Market Competitiveness:
    The LTC1421/LTC1421-2.5 stands out due to its superior performance in hot swapping, high reliability under harsh conditions, and programmability options, making it a preferred choice in demanding electronic environments.
    Application Cases and Usage Recommendations
