TC4403CPA

Overview

The TC4403CPA is a high-speed, floating load MOSFET gate driver manufactured by Microchip Technology. It features two non-inverting drivers capable of sourcing and sinking 1.5 A peak output current. The device operates on a single supply voltage ranging from 4.5 V to 18 V. Key electrical parameters include a typical rise time of 23 ns and a fall time of 25 ns. It supports CMOS and TTL logic inputs with a low quiescent supply current of 250 uA. The component is housed in an 8-pin PDIP package and is rated for operation between 0°C and +70°C.

Feature Summary

• Designed specifically for driving floating or isolated loads requiring high current pulses
• Provides dual non-inverting outputs for independent control of external switches
• Compatible with standard CMOS and TTL logic input levels

Applications

• Driving high-side N-channel MOSFETs in bridge configurations
• Power switching applications requiring isolated load drive
• Motor control circuits utilizing floating gate drivers

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm package type and temperature range. Ensure the ordering information matches the required PDIP-8 configuration. Cross-reference the manufacturer part number with authorized distributors to confirm authenticity and current production status before procurement.

Selection Notes

Select this component when a dual-channel driver for floating loads is required. It is suitable for applications needing fast switching speeds with moderate current capability. Consider the 8-pin DIP package constraint for through-hole assembly requirements. Verify that the 18 V maximum supply voltage aligns with the system power rails.

Part Context

This part belongs to the TC4403 series of MOSFET gate drivers. It is derived from the TC4425 design but optimized for floating load applications. The series focuses on providing robust drive currents for power switches while maintaining compatibility with standard digital logic interfaces.

Replacement Considerations

Official substitutes may include other Microchip floating gate drivers within the same family. Verify pinout compatibility and electrical specifications such as peak current and supply voltage range before substitution.
