Power-Down Mode

The TRF1305x2 have two bias modes, active and power-down, that are controlled by the voltage on the PD pin. The PD pin is referenced to thermal pad through a 200‑kΩ resistor; see also Section 7.2. If the VS+ ≥ 3.3 V configuration is used, ensure that the PD voltage does not exceed the Absolute Maximum Ratings in case the high PD voltage is derived from VS+.

With PD1 and PD2, control each channel independently, and individually power down each channel. Both 1.8‑V and 3.3‑V digital logic is supported for power down control.
