FAN3228TMX

Gate Driver Overview

The FAN3228TMX is a dual low-side gate driver IC manufactured by onsemi, designed for driving N-channel MOSFETs. It features two independent channels with both inverting and non-inverting inputs. The device operates within a supply voltage range of 4.5V to 18V and supports logic input levels of 0.8V (VIL) and 2V (VIH). It delivers a peak output current of 3A for both sourcing and sinking. Typical switching times are 12ns for rise and 9ns for fall. The component is housed in an 8-SOIC package and functions reliably across a temperature range of -40°C to 125°C.

Gate Driver Feature Summary

• Dual independent channel configuration supporting simultaneous control of two low-side switches
• Integrated inverting and non-inverting input options for flexible signal routing
• High peak drive capability of 3A for efficient N-channel MOSFET switching
• Robust thermal performance suitable for industrial operating environments

Gate Driver Applications

• Low-side switching in full-bridge motor drive circuits
• Power management systems requiring isolated or non-isolated gate control
• Industrial automation equipment utilizing N-channel MOSFET arrays

Gate Driver Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and tape-and-reel specifications. Confirm that the procurement source provides valid RoHS compliance data as required for regulatory adherence. Check the component status carefully, as availability may be limited due to end-of-life notifications. Ensure the supplier offers traceable manufacturing records to guarantee authenticity and quality standards.

Gate Driver Selection Notes

Select this component when dual low-side drive functionality is required with moderate current capabilities. The 8-SOIC package suits surface-mount applications with standard spacing requirements. Consider the 18V maximum supply limit when designing high-voltage systems. Verify that the 3A peak current meets the total gate charge requirements of the target MOSFETs at the intended switching frequency.
