• Manufacturer Part Number: nud3105d
• Description: Dual 5 V Inductive Load Driver
• Manufacturer: ON Semiconductor

1. Determine the maximum inductive load current (at
2. For pulsed operation, use the Transient Thermal
3. Use Figures 10 and 11 with the SOA notes to
+3.0 ≤ V
max V
temperature) that the NUD3105D will have to
drive and make sure it is less than the max rated
current.
Response of Figure 11 and the instructions with it
to determine the maximum limit on transistor
power dissipation for the desired duty cycle and
temperature range.
insure that instantaneous operation does not push
the device beyond the limits of the SOA plot.
