JAJSJS6A June 2021 – September 2021 TMAG5273
PRODUCTION DATA
Select a power multiplexer that allows powering the system from AC power line as default option. In case of power outage the power multiplexer automatically switches to back-up battery for powering the system. A status signal from, either the AC-DC regulator or the multiplexer, notifies the microcontroller on power outage events. The microcontroller, upon receiving the status signal, configures the TMAG5273 to operate in wake-up and sleep mode. The TMAG5273 will wake up and measure the magnetic field at a prespecified interval. The device repeats the cycle if no tampering happens. In case of tampering the device will exit the wake-up and sleep mode and send interrupt signal to the microcontroller.
Perform the following steps to set the device in continuous measure mode and minimize the number of steps required during battery back-up modes:
During power outage event perform only the following steps to set the sensor in the wake-up and sleep mode:
