8.8 Brownout and Blackout Conditions

The device enters a brownout condition when the input voltage drops below Vbrownout (see Figure 8-4 and Figure 8-5). This condition must be considered during design of the power supply routing, especially when operating from a battery. High-current operations, such as a TX packet or any external activity (not necessarily related directly to networking) can cause a drop in the supply voltage, potentially triggering a brownout condition. The resistance includes the internal resistance of the battery, the contact resistance of the battery holder (four contacts for 2× AA batteries), and the wiring and PCB routing resistance.

Note:

When the device is in HIBERNATE state, brownout is not detected. Only blackout is in effect during HIBERNATE state.

GUID-A0D0A2F6-A279-4D62-90FC-1E4F0A79E8CA-low.pngFigure 8-5 Brownout and Blackout Levels (2 of 2)

In the brownout condition, all sections of the device (including the 32-kHz RTC) shut down except for the Hibernate module, which remains on. The current in this state can reach approximately 400 µA. The blackout condition is equivalent to a hardware reset event in which all states within the device are lost.

Table 8-1 lists the brownout and blackout voltage levels.
