BTM7811KAUMA1

Full Half-Bridge (H Bridge) Drivers Overview

The BTM7811KAUMA1 is a half-bridge driver from Infineon Technologies, part of the TrilithIC series. It utilizes DMOS technology to drive two half-bridges for DC motor and general inductive load applications. The device operates with a supply voltage range of 1.8V to 42V and supports logic interfaces. Key electrical parameters include a peak output current of 42A, typical on-resistance of 14 mOhms for the low side and 26 mOhms for the high side. It features integrated fault protection including overtemperature, short circuit, open load detection, and UVLO. The component is housed in a PG-TO263-15-1 surface mount package and operates within a junction temperature range of -40°C to 150°C.
