CXHA3184是完全集成的电阻可编程温度开关，其阈值由外部电阻设置。它们只需要一个外部电阻器就可以在0°C到+125°C的温度范围内设置温度阈值。CXHA3184提供开漏、有源低输出。这些开关使用+4V至+5.5V的单电源工作，同时提供±0.5°C（典型值）或±3.5°C（最大值）或±3°C（60°C至+100°C）的温度阈值精度。它们通常消耗33μA的电源电流。磁滞可在10°C或30°C下选择引脚。CXHA3184有5引脚SOT-23封装
0.5°C典型阈值精度
3.5°C（最大）阈值精度（0°C至+125°C）
3°C阈值精度（60°C至+100°C）
·1%外部电阻设置的温度阈值
·低33μA电源电流
打开漏极激活低输出级
·保证复位有效至VCC=0.8V
·引脚可选择10°C或30°C滞后
