目录7.相关产品 产品概述 返回TOP CXLD64221系列产品是附带电压检测功能的高耐压正电压CMOS工艺调整器IC。内部由基准电压源, 误差放大器, 驱动晶体管, 限定电流电路, 过热保护电路, 电压检测器, 相位补偿电路等构成。输出电压及检测电压能由各自的激光微调功能在内部设定0.1V的调节间隔。内装了由反馈电路构成的过电流保护电路和过热保护电路,当输出电流达到限定电流, 或结温达到限定温度时,保护电路开始工作。CXLD64221D系列能监测调整器的输出电压,当输出电压达到指定的电压以下时,由VDOUT端子送出复位信号。复位时间(解除延迟时间)可以由外装的电容来设定。此外,CXLD64221E系列可以监测外部任意的电压,当检测出电压时,能使调整器停止输出成待机工作模式。The CXLD64221 series is a positive voltage regulator IC manufactured using CMOS process with 28V operation voltage. The series consists of a voltage reference, an error amplifier, a current limiter, a thermal shutdown circuit and a phase compensation circuit plus a driver transistor. The output voltage and the detect voltage are user selectable in 0.1V increments. The over current protection circuit and the thermal shutdown circuit are built-in. These two protection circuits will operate when the output current reaches current limit level or the junction temperature reaches temperature limit level. The CXLD64221D series monitors its output voltage and provides reset signal if its output voltage falls below the pre-set voltage. This reset time (release delay time) can be set by an external capacitor. The CXLD64221E series monitors an external power supply and enables the output to be turned off and the IC becomes a stand-by mode. 产品特点 返回TOP
