The devices are based on Allegro patented Xtreme Sense™ TMR technology with integrated CMOS process to provide a monolithic solution for superior sensing performance. The CT815x digital latches offer magnetic operation over the operating temperature range. The CT815x is an analog sensor product family that provides a linear sample-and-hold (S&H) analog output voltage with a sampling frequency of 100 Hz. The CT8152 is a TMR sensor that bines both analog and digital outputs in a single chip. It uses the digital output to turn on the analog output so that it can remain in an ultra-low power state until the analog mode is enabled. When BRP is triggered in digital mode, the analog output function will start operating. This product family has very low power consumption- as low as 1.3 µA in analog output mode and 150 n A in digital output mode- which makes it ideal for battery-operated products where minimal current consumption is required. For applications that require a very small form factor and low profile, the CT815x sensors are assembled in a 4-lead LGA...
