Overview
The MCP14628-E/MF is a dual MOSFET gate driver designed for synchronous buck converter applications. It provides high-side and low-side drive capabilities with peak output currents of 2A. The device operates from a supply voltage range of 4.5V to 5.5V. Key electrical parameters include a propagation delay of 35ns and rise/fall times of 10ns to 20ns. It features AEC-Q100 qualification for automotive reliability and operates within a temperature range of -40°C to +85°C.
Feature Summary
- Optimized for driving two N-channel MOSFETs in non-isolated synchronous buck topologies
- Provides symmetrical high-side and low-side drive outputs
- Includes AEC-Q100 automotive grade qualification
Applications
- Synchronous buck converters
- Non-isolated power supply designs
- Automotive electronic control units
Procurement Notes
Verify the specific suffix 'E/MF' corresponds to the DFN-8 package and tape-and-reel packaging configuration. Confirm that the AEC-Q100 qualification status meets your specific automotive reliability requirements. Ensure the operating voltage range aligns with your system's power rail specifications before procurement.
Selection Notes
Select this component when a compact, dual-channel driver is required for synchronous rectification. The DFN-8 package offers a small footprint suitable for space-constrained designs. Consider the 2A peak current capability as sufficient for moderate-power MOSFETs. Verify thermal performance requirements given the exposed pad design.
Part Context
This part belongs to Microchip's MCP1462x series of synchronous buck drivers. It is specifically engineered to replace discrete driver solutions in DC-DC converter circuits. The family focuses on providing integrated protection features and fast switching speeds for efficient power management.
Replacement Considerations
Check for direct pin-compatible alternatives within the MCP1462x family. Verify if higher current variants are needed for larger MOSFETs. Ensure substitute parts maintain the same DFN-8 package dimensions and thermal characteristics.
