目录7.相关产品 产品概述 返回TOP CXLD64217是内置了电压检测器的具有高精度,低噪声,大电流,低压差,正电压输出的电压调整器系列。该系列采用了CMOS工艺技术,内部由基准电压电路,误差放大电路,限流电路,电压检测电路,相位补偿电路以及一个驱动三极管组成。电压调整器LDO以及电压检测器VD的电压输出大小可以在0.8V到5.0V之间的范围内以50mV为间隔自由选择。通过内置低导通电阻的驱动三极管,即使在电池输入输出压差很小的情况下仍可以正常工作,从而延长了电池的使用寿命。该系列可兼容低ESR的陶瓷电容,使得输出更稳定。根据不同的电路特征,CXLD64217系列提供给客户更多方面的选择,比如,电压检测的监测,电压检测的输出逻辑,使能端子的控制逻辑以及内部上/下拉电阻的选择(客户定制)等等。CXLD64217C系列通过控制使能端子EN,可以使得内置的电压调整器处于待机状态。在待机工作模式时,功耗被大大的降低了。可以通过改变外部连接电容Cd的容量值来调节电压检测器输出延迟时间长短。The CXLD64217 series are precise, low noise, high current, positive voltage low dropout regulators with built-in voltage detector. They are fabricated using Torex’s CMOS process. The series features a voltage reference, an error amplifier, a current limiter, a voltage detector and a phase compensation circuit plus a driver transistor. The output voltage of the LDO and detect voltage of the detector is selectable in 50mV increments within the range of 0.8V to 5.0V. With a low ON resistance driver transistor built-in, batteries can be used until input-output voltage differential is minimal and can accordingly be used for a longer time. The series is also compatible with low ESR ceramic capacitors which give added output stability. The series provides options to the user to select from a variety of circuit features, such as detector monitoring, detector output logic, EN pin input logic, and internal pull-up / down resistance (semi-custom). The IC's internal regulator circuit can be placed in stand-by mode via the EN function (CXLD64217C series). In the stand-by mode, power consumption is greatly reduced. The CXLD64217F series offers the option of a delay on the detector output: the delay time can be controlled by the use of an external capacitor. 产品特点 返回TOP
