ICC80QSG集成電路（IC）的電池充電器規(guī)格書PDF中文資料

ICC80QSG屬于集成電路（IC）的電池充電器。由英飛凌科技股份公司制造生產(chǎn)的ICC80QSG電池充電器電池充電器 PMIC（電源管理集成電路）是元器件級產(chǎn)品系列，用于在電子設備中實現(xiàn)電池充電控制和充電管理功能。這些器件主要根據(jù)電池化學及其設計用于的電池數(shù)量來分類，可提供電化學電池和超級電容器安全充電所必需的電流或電壓調節(jié)和監(jiān)視功能。

Features

The ICC80QSG flyback controller is tailored for battery charger application to meet the required performance.

Features

? Secondary side regulation (SSR), for battery charging current control

? High efficiency and low electromagnetic interference (EMI) with quasi-resonant valley switching

? Quasi-resonant mode (QRM) operation with continuous conduction mode (CCM)-prevention and valley

switching discontinuous conduction mode (DCM) in mid to light load

? Burst mode for very light loads and low system standby power consumption

? Reduced gate driver output voltage during burst mode for lower standby power

? Adjustable on-time mapping at valley changing position, for the desired maximum operating switching

frequency

? Adjustable maximum on-time – limits input power and current allowing safe-operation under low line

condition

? Comprehensive set of protections:

- internal overtemperature protection (OTP)

- flyback output overvoltage protection (OVP)

- primary side over-current protection (OCP)

- brownin protection

- brownout protection

- VCC overvoltage protection

- open loop protection

- input overvoltage protection

? Externally configurable hysteresis of brownin and brownout

? Adaptive brownout level triggering based on bus voltage ripple - protect primary components from

overheating and saturation with higher brownout level at higher input/output power

? Supports on/off control with external pull-down signal

? Soft start to reduce component stress during turn-on

? External start-up circuit control signal
