CXHA3151 CXHA3152 CXHA3153采用混合信号CMOS工艺制造。它内部包括一个片上霍尔电压发生器、一个工作电压为1.8到5.5V的电压调节器、一个低功耗的休眠/唤醒逻辑、温度补偿电路、小信号放大器、带有动态偏移抵消系统的霍尔传感器、施密特触发器和开漏输出。无论是北极还是南极,只要有足够的强度,传感器输出就会开启。在没有磁场的情况下,输出将关闭。当磁通密度(B)大于工作点(Bop)时,将打开输出(低),保持输出直到B低于释放点(Brp),然后关闭。在2.7V电源下,正常运行时的总功耗通常为10μW。CXHA3151 CXHA3152 CXHA3153的工作温度范围为-40°C至85°C。

产品概述 返回TOP
The CXHA3151 CXHA3152 CXHA3153 is fabricated from mixed signal CMOS technology. It internally includes an on-chip Hall voltage generator, a voltage regulator for operation with supply voltages of 1.8 to 5.5V, a sleep/awake logic for low power consumption, temperature compensation circuitry, small-signal amplifier, Hall sensor with dynamic offset cancellation system, Schmitt trigger and an open-drain output. Either north or south poles of sufficient strength will turn the sensor output on. The output will be turned off under no magnetic field. While the magnetic flux density (B) is larger than operating point (Bop), the output will be turned on (low), the output is held until B is lower than release point (Brp), and then turned off. The total power consumption in normal operation is typically 10μW with a 2.7V power source. Operating temperature range of the CXHA3151 CXHA3152 CXHA3153 is from -40°C to 85°C.
