LTC4150
APPLICATIONS INFORMATION
AUTOMATIC CHARGE COUNT INTERRUPT AND CLEAR
In applications where a CLR pulse is unavailable, it’s easy to
make the LTC4150 run autonomously, as shown in Figures
5 and 6. If the microcontroller V CC is less than or equal to
the battery V DD , INT may be directly connected to CLR , as
in Figure 5. The only requirement is that the microcontroller
should be able to provide a high logic level of 1.9V to SHDN .
use Figure 6. The resistor dividers on CLR and SHDN keep
the voltages at these pins within the LTC4150’s V DD range.
Choose an R L value using Equation 11 and R1-R4 values
using Equation 13. In either application, the LTC4150 will
capture the ?rst assertion of INT and wait at least 1μs
before resetting it. This insures that INT pulses low for at
least 1μs but gives automatic INT reset.
If the microcontroller V CC is greater than the battery V DD ,
