6 Device Requirements and Characteristics (continued)
6.3
Recommended Operating Conditions
6.4
Decoupling Requirements
Install a high-quality ceramic 0.01 pF capacitor between each VDD pin and ground. Install each capacitor as close
as possible to the B900 package. Also, install an additional 0.47
F—1.0 F capacitor at only one of the VDD pins.
6.5
Package Thermal Considerations
The recommended operating temperature specified in Table 89 is based on the maximum power, package type,
and maximum junction temperature. The following equations describe the relationship between these parameters.
If the application’s maximum power is less than the worst-case value, this relationship determines a higher maxi-
mum ambient temperature or the maximum temperature measured at top dead center of the package.
TA = TJ – P x
ΘJA
TTDC = TJ – P x
ΘJ – TDC
where TA is the still-air ambient temperature and TTDC is the temperature measured by a thermocouple at the top
dead center of the package.
Warning: Due to package thermal constraints, proper precautions in the user’s application should be taken
to avoid exceeding the maximum junction temperature of 125 °C. Otherwise, the device will be
affected adversely.
