NUD3105D Integrated Relay, Inductive Load Driver
This device is used to switch inductive loads such as relays, solenoids incandescent lamps, and small DC motors without the need of a free-wheeling diode. The device integrates all necessary items such as the MOSFET switch, ESD protection, and Zener clamps. It accepts logic level inputs thus allowing it to be driven by a large variety of devices including logic gates, inverters, and microcontrollers.

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected. 1. This device contains ESD protection and exceeds the following tests: Human Body Model 2000 V per MIL_STD-883, Method 3015. Machine Model Method 200 V.

Designing with this Data Sheet
1. Determine the maximum inductive load current (at max VCC, min coil resistance & usually minimum temperature) that the NUD3105D will have to drive and make sure it is less than the max rated current. 2. For pulsed operation, use the Transient Thermal 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. 3. Use Figures 10 and 11 with the SOA notes to insure that instantaneous operation does not push the device beyond the limits of the SOA plot.
4. Verify that the circuit driving the gate will meet the VGS(th) from the Electrical Characteristics table. 5. Using the max output current calculated in step 1, check Figure 7 to insure that the range of Zener clamp voltage over temperature will satisfy all system & EMI requirements. 6. Use IGSS and IDSS from the Electrical Characteristics table to insure that "OFF" state leakage over temperature and voltage extremes does not violate any system requirements. 7. Review circuit operation and insure none of the device max ratings are being exceeded.
