AT58MP1T1RDC (AT5812C)

Low power consumption (0.37mA to 14mA), with direct output of control signals, making it suitable for products with flexible power consumption adjustment requirements as well as those with higher performance needs.

5.8GHz series chips

AT58MP1T1RDC (AT5812C)

Product Features

Operating in the 5.8 GHz ± 75 MHz frequency band, this fully integrated microwave sensor chip features ultra-low power consumption (0.37–14 mA) and adopts an ultra-low-power architecture. The chip integrates a signal processor internally, enabling it to directly output sensing control signals. With just a few external components, it can be readily configured into a complete microwave sensing sensor. Compared to the previous generation, this chip boasts lower power consumption, more flexible power adjustment, and enhanced anti-interference capability.
