For Recommended soldering conditions see Tech Brief TB389.
CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the
device at these or any other conditions above those indicated in the recommended operating conditions of this specification is not implied.
NOTES:
1. All voltages referenced to V_SS unless otherwise specified.
2. Based on V_DD=15V. The magnitude of the allowable negative transient on the HS pin is a function of the V_DD supply voltage. V_HS<15.6V-
V_DD+V_F, where V_HS is the magnitude of the allowable negative transient and V_F is the forward voltage drop of the bootstrap diode.
3. θ_JA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
4. θ_JA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. θ_JC, the
“case temp” is measured at the center of the exposed metal pad on the package underside. See Tech Brief TB379.
