TC1428COA

Gate Driver Overview

The TC1428COA is a dual low-side MOSFET gate driver manufactured by Microchip Technology. It provides independent inverting and non-inverting outputs with peak source and sink currents of 1.2A each. The device operates within a supply voltage range of 4.5V to 16V and supports CMOS and TTL logic inputs at 0.8V and 3V respectively. Typical rise and fall times are 35ns and 25ns. It is housed in an 8-SOIC package (0.154 inch width) and functions within a temperature range of 0°C to 70°C.

Gate Driver Feature Summary

• Provides dual independent low-side drive capabilities with distinct inverting and non-inverting output configurations for flexible control schemes.
• Delivers high peak output current of 1.2A to ensure rapid switching of power MOSFETs, minimizing transition losses.
• Compatible with standard CMOS and TTL logic levels, allowing direct interfacing with various microcontrollers and digital signal processors.

Gate Driver Applications

• Driving N-channel and P-channel power MOSFETs in motor control circuits
• Gate driving in DC-DC converter topologies requiring low-side switching
• Inverter bridge applications utilizing complementary low-side FET arrangements

Gate Driver Procurement Notes

Verify the specific suffix 'COA' corresponds to the SOIC-8 tube packaging configuration when ordering. Confirm that the AEC-Q100 qualification status aligns with automotive application requirements if applicable. Ensure the operating temperature range of 0°C to 70°C meets the environmental constraints of the target system design.

Gate Driver Selection Notes

Select this component when dual independent low-side drive is required with moderate speed performance. The 1.2A output current is suitable for medium-power MOSFETs. Consider the 8-SOIC package for surface-mount assembly. Compare against TC1427COA if only non-inverting outputs are needed, or TC1426COA if only inverting outputs are sufficient.

Gate Driver Part Context

The TC1428COA belongs to the TC142x series of high-speed MOSFET gate drivers from Microchip Technology. This series includes variants like TC1426, TC1427, and TC1428, which differ primarily in their input/output logic configurations. The TC1428 specifically combines both inverting and non-inverting channels in a single package.

Gate Driver Replacement Considerations

TC1427COA offers identical electrical characteristics but provides two non-inverting outputs instead of one inverting and one non-inverting. TC1426COA provides two inverting outputs. Both alternatives share the same package, current ratings, and supply voltage ranges.
