5.8 Brownout and Blackout Conditions
The device enters a brownout condition when the input voltage dips below V
BROWNOUT
(see Figure 5-4 and
Figure 5-5). This condition must be considered during design of the power supply routing, especially if
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, contact resistance of the
battery holder (four contacts for a 2× AA battery), and the wiring and PCB routing resistance.
NOTE
When the device is in the Hibernate state, brownout is not detected; only blackout is in effect
during the Hibernate state.
Figure 5-4. Brownout and Blackout Levels (1 of 2)
Figure 5-5. Brownout and Blackout Levels (2 of 2)
In the brownout condition, all sections of the CC3135MOD (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.
