and Reverse Battery, Short Circuit, and Thermal Shutdown Protection  
Application Information  
Two typical application circuits are shown in figures 4 and 5. The A bypass capacitor of 0.1 μF is required between VDD and GND  
¯¯¯¯¯¯¯¯  
first application circuit shows the device SLEEP pin controlled  
for proper device operation through the full specified supply volt-  
age range.  
by the user. Figure 5 illustrates an application circuit where the  
¯¯¯¯¯¯¯¯  
device VDD and SLEEP pin are connected together.  
Note that:  
No external diode is required for reverse battery protection  
because the protection is fully integrated into the IC.  
Thermal shutdown is integrated also.
