Page 5 and Page 6
1.EN Input Low Level Threshold
a.T = 25C specifications changed from MIN = 1.4; TYP = 1.8 to MIN = 1.8; TYP = 2.5
b.Full Temperature specifications changed from MIN = 1.2 to MIN = 1.8
2.EN Input High Level Threshold
a.T = 25C specifications changed from TYP = 1.8; MAX = 2.2 to TYP = 2.8; MAX = 4.
b.Full Temperature specification change from MAX = 2.4 to MAX = 4.1
3.EN Pull-Up Resistance changed to EN Pull-Down Resistor. Resistance value unchanged. This is to correct
previous datasheet revision error. Not a functional change to the die.
4.Under Voltage Protection VDD Rising Threshold
a.MAX limit changed from 8.1V to 8.0V
5.Bootstrap Diode
a.Low Current Forward Voltage: Changed test condition from 100mA to 100µA. This is to correct previous
datasheet revision error. Not a functional change to the test.
b.Dynamic Resistance: Test condition clarified. Added formula to calculate dynamic resistance at 50mA and
100mA diode current. This is to correct previous datasheet revision error. Not a functional change to the test.
6.Switching Specification Test Condition: Changed RDT = 0kΩ to RDT = 8kΩ or 80kΩ.
7.Added Dead Time Delay Matching Specifications for RDT at 8kΩ and 80kΩ.
Page 7 to Page 9
1.Updated Figures Figures 3 through 6 for clarity.
2. Figure 7 (High Level Output Voltage vs Temp) and Figure 8 (Low Level Output Voltage vs Temp) moved to
Figures 11 and 12 and updated for clarity.
3. Figure 9 (UVLO Rising Threshold) and Figure 10 (UVLO Hysteresis) moved to Figures 15 and 16 and revised for
clarity.
4. Figure 11 (Propagation Delay vs Temp) moved to Figure 7 and updated for clarity.
5. Figure 12 (Delay Matching vs Temp) removed.
6. Figure 13 (Peak Pull-up Current) and Figure 14 (Peak Pull-down Current) updated for clarity.
7. Figure 15 (Quiescent Current vs Voltage) moved to Figures 19 and 20 and updated for clarity.
8.Figure 16 moved to Figure 10 and updated for clarity.
9.Removed Figure 17 (VHS Voltage to VDD Voltage Derating)
10.Added additional Typical Performance Curves for Output Impedance vs Temp and PWM Threshold Voltages
Page 10 to Page 12

2.Added to Applications Section: Input Capacitor
3.Added to Application Section: Dead Time Delay
4.Added to Application Section: High Voltage Conductor Spacing
5.Application Section: Transient On HS Node updated with new content
6. Equation 1 updated to fix format error.
7. Equation 3 updated to fix error.
