MCP14A0155-E/SN

Overview

The MCP14A0155-E/SN is a dual low-side MOSFET gate driver from Microchip Technology, housed in an 8-pin SOIC package. It operates on a single supply voltage ranging from 4.5 V to 18 V and delivers a peak output current of 1.5 A per channel. The device features complementary (non-inverting) outputs, allowing for direct drive of high- and low-side switches in half-bridge configurations without external logic inversion. Designed for industrial applications, it supports a wide operating temperature range from -40°C to +125°C.

Feature Summary

• Dual complementary output configuration suitable for half-bridge driving
• High peak source/sink current capability of 1.5 A per channel
• Wide single-supply voltage operation from 4.5 V to 18 V
• Extended industrial temperature range up to +125°C

Applications

• Industrial motor control systems
• Power supply designs requiring half-bridge topologies
• Inverter circuits for AC drives
• Battery management system switching applications

Procurement Notes

Verify the complete part number including suffixes such as -E/-I/-M for temperature grades and -SN/-MS for packages against official Microchip documentation. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure ordering quantities match tube packaging specifications provided by authorized distributors.

Selection Notes

Select this component when a dual non-inverting low-side driver is required for half-bridge applications. Compare with MCP14A0153 and MCP14A0154 if inverting or non-inverting single-output configurations are needed instead. Consider the SOIC-8 package constraints regarding thermal dissipation and PCB layout space relative to alternative QFN packages in the same family.

Part Context

This device belongs to the MCP14A01xx series of low-side gate drivers. It shares core electrical characteristics with variants like MCP14A0153 and MCP14A0154, differing primarily in output logic configuration. The series is designed for robust performance in noisy industrial environments, offering fast switching speeds and high current drive capabilities within a compact surface-mount footprint.

Replacement Considerations

Direct functional substitutes include MCP14A0153-E/SN and MCP14A0154-E/SN, though these offer different logic inversions. Verify pin compatibility and output configuration requirements before substitution. Alternative packages such as MSOP may require re-evaluation of thermal and mechanical constraints.
