IFXBTN8982TA
Overview
The BTN8982TA is an integrated high-current half-bridge motor driver from the NovalithIC family designed for automotive and industrial motor drive applications. It combines a p-channel high-side MOSFET and an n-channel low-side MOSFET with a complete driver IC in a single package. The device features integrated protection such as current limiting, overtemperature shutdown, and undervoltage lockout to simplify robust motor control designs.
Why Choose This Part
The BTN8982TA provides a very low typical Rds(on) of 4.7mOhm (LS) and 5.3mOhm (HS) to minimize thermal losses in high-current applications. It features an adjustable slew rate via an external resistor to optimize electromagnetic compatibility (EMC) and switching losses. Additionally, the integrated current sense capability and logic-level inputs significantly reduce external component count and PCB footprint.
Applications
Key Specifications
Getting Started
When designing with the BTN8982TA, ensure that an external resistor is connected to the SR pin to set the desired slew rate for your PWM frequency. A ceramic capacitor should be placed very close to the Vs and GND pins to handle high-frequency switching noise. For rapid prototyping, the Infineon DC Motor Shield for Arduino uses similar NovalithIC drivers and provides a convenient hardware platform for software development.
