SM72482MA-4/NOPB

Gate Driver Overview

The SM72482MA-4/NOPB is a dual compound gate driver from the SolarMagic series by Texas Instruments. It features two drivers with inverting and non-inverting configurations, housed in an 8-SOIC package. The device operates on a supply voltage range of 3.5 V to 14 V, delivering a peak output current of 5 A. Key timing parameters include rise and fall times of 14 ns and 12 ns, respectively, with maximum on/off delays of 25 ns. It functions within a temperature range of -40°C to +125°C and consumes approximately 1 mA of quiescent current.

Gate Driver Feature Summary

• Provides dual independent gate drive channels with complementary inverting and non-inverting outputs for bridge control applications.
• Utilizes compound architecture to deliver high peak sink and source currents for rapid MOSFET switching.
• Designed for robust operation across extended industrial temperature ranges with low power consumption.

Gate Driver Applications

• Solar inverter systems
• Motor drive circuits
• High-frequency power conversion topologies

Gate Driver Procurement Notes

Verify the manufacturer designation as Texas Instruments, as the component belongs to their SolarMagic portfolio despite historical brand associations. Confirm the specific suffix /NOPB indicates lead-free and RoHS compliance. Ensure the SOIC-8 package type matches the target PCB footprint requirements before procurement.

Gate Driver Selection Notes

Select this component when dual-channel gate driving with distinct phase inversion is required for half-bridge or full-bridge configurations. The 5 A output capability suits medium-power MOSFETs. Consider the 3.5 V minimum supply voltage for compatibility with standard logic levels and the wide operating temperature range for harsh environments.

Gate Driver Part Context

This part is part of the SM72482 family, specialized for solar energy applications under the SolarMagic branding. It serves as a dedicated interface between control logic and power switches, optimizing efficiency in photovoltaic inverters and DC-DC converters through fast, reliable switching characteristics.

Gate Driver Replacement Considerations

Check for direct equivalents within the SM72482 family or other Texas Instruments dual gate drivers with similar pinouts and electrical specifications. Verify that any substitute maintains the 5 A output current and 8-SOIC package form factor.

Gate Driver FAQ

What is the difference between the two outputs?

The device provides one inverting and one non-inverting output, allowing for complementary drive signals necessary for half-bridge or full-bridge topologies without external logic inversion.

Is this component suitable for high-temperature environments?

Yes, the SM72482MA-4/NOPB is rated for operation up to +125°C, making it suitable for demanding industrial and automotive-grade applications.
