Power-OK and Low-Battery-Detect Functionality
LBO goes low in startup mode as well as during normal operation if:
- The voltage at the LBI pin is below LBI threshold (0.6V). This can be used to monitor the battery voltage.
- LBI pin is connected to GND and V OUT is below 92.5% of its nominal value. LBO works as a power-OK signal in this case.
The LBI pin can be connected to a resistive-divider to monitor a particular definable voltage and compare it with a 0.6V internal reference. If LBI
is connected to GND an internal resistive-divider is activated and connected to the output. Therefore, the Power-OK functionality can be realized
with no additional external components.
The Power-OK feature is not active during shutdown and provides a power-on-reset function that can operate down to V IN = 0.7V. A capacitor to
GND may be added to generate a power-on-reset delay. To obtain a logic-level output, connect a pull-up resistor R 3 from pin LBO to pin VOUT.
Larger values for this resistor will help to minimize current consumption; a 100k Ω resistor is perfect for most applications (see Figure 16 on page
13) .
For the circuit shown in the left of Figure 15 , the input bias current into LBI is very low, permitting large-value resistor-divider networks while
maintaining accuracy. Place the resistor-divider network as close to the device as possible. Use a defined resistor for R 2 and then calculate R 1
as:
R 1 = R 2 ? ? ----------- – 1 ?
