Notes
7.
Pin soldering temperature limit is for 10 seconds maximum duration. Not designed for immersion soldering. Exceeding these limits may
cause malfunction or permanent damage to the device.
8.
Freescale’s Package Reflow capability meets Pb-free requirements for JEDEC standard J-STD-020C. For Peak Package Reflow
Temperature and Moisture Sensitivity Levels (MSL),
9.
Exposed heatsink pad plus the power and ground pins comprise the main heat conduction paths. The actual RθJB (junction-to-PC board)
values will vary depending on solder thickness and composition and copper trace thickness and area. Maximum current at maximum
die temperature represents ~16 W of conduction loss heating in the diagonal pair of output MOSFETs. Therefore, the RθJA must be
<5.0°C/W for maximum current at 70°C ambient. Module thermal design must be planned accordingly.
Table 2. Maximum Ratings (continued)
All voltages are with respect to ground unless otherwise noted. Exceeding these ratings may cause a malfunction or
permanent damage to the device. These parameters are not production tested.
