CXHA3188是完全集成的电阻可编程倍频程远程温度开关，具有可选的外部/内部触发电压设置。阈值由外部电阻和负温度系数热敏电阻设定。CXHA3188为每2个传感器提供4个开路、低激活、超温输出。这些开关在+2.7V至+5.5V的单电源下工作。CXHA3188有16针TQFN3X3-16封装
8个由热敏电阻和外部电阻设置的远程温度开关
每2个温度开关有4个开漏有源低输出级
可选外部/内部触发电压设置
使用内部设置触发电压时的内置滞后温度
保证输出信号对VCC有效=0.8V

产品概述 返回TOP
The CXHA3188 are fully integrated, resistor programmable octave remote temperature switches with selectable external/internal trigger voltages setting. The thresholds are set by external resistors and thermistor with negative temperature coefficient. The CXHA3188 provides 4 open-drain, active low, over-temperature outputs for each 2 sensors. These switches operate with a +2.7V to +5.5V single supply. The CXHA3188 are available in 16-pin TQFN3X3-16 packages.
