Power Dissipation
32QFN PD1
- 3.9 W Ta=25°C (Note 4, Note 5)
- 2.0 W Ta=85°C (Note 4, Note 5)
24QFN PD2
- 3.1 W Ta=25°C (Note 4, Note 5)
- 1.6 W Ta=85°C (Note 4, Note 5)
Junction Temperature Tj - 150 °C

Note 2. All above voltages are with respect to GND. The each power supply of VC and VM is sequence-free.
Note 3. For Power Dissipation, the output current rating may be limited by duty cycle, Ta, and PCB board heat
sinking design.
Note 4. Exposed Pad must be connected to GND.
Note 5. A 4-layer JEDEC51 compliant board is used.
If the temperature exceeds 25°C, be sure to derate at Figure 2.
24-pin QFN: R JA =40°C /W
32-pin QFN: R JA =32°C /W
WARNING: Operation at or beyond these limits may result in permanent damage to the device. Normal
operation is not guaranteed at these extremes.
