MCP14A0155T-E/MS

Overview

The MCP14A0155T-E/MS is a dual MOSFET gate driver manufactured by Microchip Technology, housed in an 8-MSOP surface-mount package. It provides complementary output configurations with peak drive currents of 1.5 A for both sourcing and sinking. The device operates within a supply voltage range of 4.5 V to 18 V and supports low input threshold signals. Key electrical parameters include rise and fall times of approximately 11.5 ns under capacitive load conditions. It functions reliably across an extended temperature range from -40°C to +125°C junction temperature.

Feature Summary

• Dual complementary output configuration for driving high-side and low-side MOSFETs
• Low input threshold capability allowing direct interface with various logic families
• Integrated enable pin for controlling driver operation state

Applications

• Motor control systems requiring precise gate drive timing
• Power supply topologies utilizing synchronous rectification
• Industrial automation inverters and converters

Procurement Notes

Verify the specific suffix 'E/MS' corresponds to the 8-MSOP package and automotive-grade temperature rating when ordering. Confirm that the datasheet revision matches your design requirements, as pinout or electrical characteristics may vary between revisions. Ensure compatibility with your PCB footprint dimensions for the MSOP-8 package before finalizing procurement.

Selection Notes

Select this component when a dual-channel driver with low-voltage logic compatibility is required. The 1.5 A drive current suits medium-power MOSFET applications. Consider the 8-MSOP package size constraints and thermal dissipation needs. Verify that the 4.5 V minimum supply voltage aligns with your system's available rail. Compare against single-channel alternatives if only one side of a bridge is needed.

Part Context

This part belongs to the MCP14A series of MOSFET gate drivers from Microchip Technology. The series includes variants with different drive currents and package options, such as the MCP14A0152T-E/MAY (single channel) and MCP14A0455T-E/MSVAO (higher current). The MCP14A0155T-E/MS specifically offers a balanced dual-channel solution in a compact form factor suitable for space-constrained designs.

Replacement Considerations

Direct substitutes include other MCP14A0155 variants with different packages, such as MCP14A0155T-E/MNY (TDFN-8) or MCP14A0155T-E/SN (SOIC-8), provided the pinout is compatible. Cross-reference with similar dual 1.5 A drivers from other manufacturers only if electrical specifications and pin assignments match exactly.
