Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected. 2. Maximum electrical ratings are defined as those values beyond which damage to the device may occur at TA = +25°C. 3. The thermal shutdown set to 160 °C (typical) avoids irreversible damage on the device due to power dissipation. For further information see page 6. 4. For the 9−Pin Flip−Chip CSP package, the RqJA is highly dependent of the PCB Heatsink area. For example, RqJA can equal 195°C/W with 50 mm2 total area and also 135 °C/W with 500 mm2. For further information see page 10. The bumps have the same thermal resistance and all need to be connected to optimize the power dissipation. 5. Human Body Model, 100 pF discharge through a 1.5 k W resistor following specification JESD22/A114. 6. Machine Model, 200 pF discharged through all pins following specification JESD22/A115. 7. Maximum ratings per JEDEC standard JESD78. |
