UCSP Reliability  
Figure 3 shows a zero-crossing detector application.  
The chip-scale package (UCSP) represents a unique  
packaging form factor that may not perform equally to a  
packaged product through traditional mechanical relia-  
bility tests. UCSP reliability is integrally linked to the  
users assembly methods, circuit board material, and  
usage environment. The user should closely review  
these areas when considering use of a UCSP package.  
Performance through Operating Life Test and Moisture  
Resistance remains uncompromised as it is primarily  
determined by the wafer-fabrication process.  
The MAX985s inverting input is connected to ground,  
and its noninverting input is connected to a 100mV  
P-P  
signal source. As the signal at the noninverting input  
crosses 0V, the comparators output changes state.  
Logic-Level Translator  
Figure 4 shows an application that converts 5V logic lev-  
els to 3V logic levels. The MAX986 is powered by the 5V  
supply voltage, and the pullup resistor for the MAX986s  
open-drain output is connected to the 3V supply voltage.  
This configuration allows the full 5V logic swing without  
creating overvoltage on the 3V logic inputs. For 3V to 5V  
logic-level translation, simply connect the 3V supply to  
Mechanical stress performance is a greater consideration  
for a UCSP package. UCSPs are attached through direct  
solder contact to the users PC board, foregoing the  
inherent stress relief of a packaged product lead frame.  
Solder joint contact integrity must be considered.  
Information on Maxims qualification plan, test data, and  
recommendations are detailed in the UCSP application  
note, which can be found on Maxims website at  
www.maxim-ic.com.
