TDA7073AT/N4,118

Full Half-Bridge (H Bridge) Drivers Overview

The TDA7073AT/N4,118 is a dual bridge-parallel (BTL) power driver integrated circuit manufactured by NXP Semiconductors. Designed for driving DC motors and general-purpose loads, it features two independent drivers capable of delivering up to 600 mA output current per channel. The device operates within a supply voltage range of 3 V to 18 V and functions reliably across an extended temperature range from -55 °C to +150 °C. It is housed in a 16-lead Small Outline Package (SOIC-16) with a 1.27 mm pitch, suitable for surface-mount assembly.

Full Half-Bridge (H Bridge) Drivers Procurement Notes

Verify the exact suffix and revision level against official NXP documentation, as obsolete status may limit availability. Confirm RoHS compliance and REACH directive adherence through certified datasheets. Ensure the SOIC-16 package dimensions match your PCB footprint requirements before ordering.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Select this component when a single IC solution is required for driving two DC motors or one high-current load in a BTL configuration. Consider the 600 mA continuous current rating and 18 V maximum supply voltage limits. Evaluate thermal management needs given the 150 °C max operating temperature and SOIC-16 package constraints.

Full Half-Bridge (H Bridge) Drivers Part Context

This part belongs to NXP's TDA70xx series of audio and motor driver ICs. The TDA7073AT variant specifically targets dual bridge-parallel applications, distinguishing itself from standard half-bridge or single-channel drivers. It is designed for robustness in automotive and consumer environments requiring reliable motor actuation.
