Manufacturer: Infineon Technologies

Categories: Full Half-Bridge (H Bridge) Drivers

Quality Control: Learn More

Infineon Technologies NovalithIC™ BTN7973BAUMA1 is a half-bridge driver designed for DC motor control and general-purpose applications. This DMOS technology component offers high current capabilities, with a continuous output of 44A per channel and a peak output of 90A. Featuring low on-state resistance, 9mOhm typ. for the low-side switch and 7mOhm typ. for the high-side switch, it ensures efficient power delivery. The device operates from a 4.5V to 28V supply voltage and is suitable for inductive loads. Advanced fault protection mechanisms are integrated, including current limiting, over-temperature, over-voltage, short-circuit, and undervoltage lockout (UVLO). Additional features include a latch function, slew rate control, and a status flag for operational monitoring. The BTN7973BAUMA1 is available in a PG-TO263-7-1 package suitable for surface mounting and operates within an ambient temperature range of -40°C to 150°C. Its robust design makes it suitable for automotive and industrial automation sectors.

Integrated Circuit FAQs

An integrated circuit (IC) is a semiconductor chip that contains transistors, resistors, capacitors, and other electronic components on a single silicon substrate. ICs are the foundation of modern electronics and power devices such as smartphones, computers, automotive systems, and industrial equipment.

Integrated circuits work by routing electrical signals through microscopic semiconductor components fabricated onto a silicon chip. Depending on the design, ICs can process, amplify, store, or control electronic data.
