UCC3956N概述

    Comprehensive Analysis of the UCC3956 Lithium-Ion Battery Charger Controller
    Product Introduction:
    The UCC3956 series of switch-mode lithium-ion battery charger controllers represents a breakthrough in efficient charging solutions for lithium-ion batteries. These devices are specifically designed for applications involving single-cell or multi-cell lithium-ion battery packs. With advanced features like high-efficiency average-current control loops, programmable overcharge times, and integrated charge-state logic, the UCC3956 family stands out as a versatile and reliable solution.
    The controller's primary purpose is to optimize the charging process of lithium-ion batteries, ensuring safe and effective charging across various stages, from trickle charge to full overcharge. The product supports high-side or low-side switch-mode current sensing, providing flexibility for different circuit configurations.
    Technical Parameters:
    The UCC3956 comes equipped with a comprehensive set of technical specifications:
    - Supply Voltage Range: 6 V to 18 V.
    - Charge States: Trickle, Bulk, Overcharge, and Top-off.
    - Current Sensing: Fixed gain of 5.
    - PWM Duty Cycle: Up to 100%.
    - Timer Frequency: Adjustable via the CTO pin, ranging from 0.75 Hz to 5 Hz.
    - Pin Descriptions:
    - CAO: Output of the current-error amplifier.
    - STAT0 & STAT1: Binary outputs indicating charge states.
    - RSET: Programs charge current for the oscillator ramp.
    Performance metrics such as CMRR (50-65 dB), bandwidth (up to 3 MHz), and initial accuracy (4.06-4.14 V) highlight the precision and robustness of the UCC3956.
