Overview
The TC4403MJA is a dual high-speed MOSFET gate driver manufactured by Microchip Technology, designed for floating load applications. It features two non-inverting outputs capable of sourcing and sinking 1.5 A peak current. The device operates within a supply voltage range of 4.5 V to 18 V and accepts CMOS or TTL logic inputs. Key electrical parameters include a typical rise time of 23 ns and fall time of 25 ns, with a quiescent supply current of 250 µA. It is housed in an 8-pin ceramic dual in-line package (CDIP) and supports an operating temperature range from -55°C to +125°C.
Feature Summary
- Provides dual independent high-current drive channels for efficient switching of power MOSFETs.
- Supports floating load configurations suitable for high-side driving applications without external bootstrap requirements.
- Compatible with standard CMOS and TTL logic levels for direct interface with microcontrollers.
Applications
- High-side switching in motor control circuits
- Power supply management systems requiring isolated gate drive
- Industrial automation equipment utilizing MOSFET-based inverters
Procurement Notes
Verify the specific suffix MJA indicates the ceramic DIP package and extended industrial temperature range. Confirm RoHS compliance status through official documentation as historical variants may differ. Ensure the source document matches the manufacturer's current datasheet revision to validate pinout and electrical characteristics against legacy specifications.
Selection Notes
Select this component when a ruggedized ceramic package is required for harsh environments due to its wide temperature tolerance. Compare against plastic DIP versions if cost reduction is prioritized over thermal stability. Verify that the 1.5 A output current meets the gate charge requirements of the target MOSFETs at the intended switching frequency.
Part Context
This part belongs to the TC4403 series of single-supply MOSFET drivers. It shares functional similarities with the TC4403CPA and TC4403EPA but differs in packaging material and operational temperature limits. The MJA suffix specifically denotes the hermetic ceramic construction, distinguishing it from standard plastic packages within the same logical family.
Replacement Considerations
TC4403CPA: Plastic DIP variant with commercial temperature range. TC4403EPA: Plastic DIP variant with extended temperature range. TC4403MJA is the ceramic equivalent; verify package compatibility before substitution.
