Design a Custom BoardAbout This Component
Dual-bridge motor driver IC with integrated DMOS output transistors capable of driving two DC brushed motors or one stepper motor. Features 1.1A max output current, 18V motor supply, 0.8Ω typical on-resistance, and includes over-current detection, thermal shutdown, and under-voltage lockout protection circuits for robust motor control applications.
Package: TSSOP-16 (4.4×5mm) · 16 pins
Why does this need a breakout?
The 0.65mm pitch makes hand soldering difficult and error-prone; a breakout board lets you solder standard headers instead. This package hosts precision analog and mixed-signal ICs like DACs and ADCs that benefit from clean PCB layouts and decoupling placement. Prototyping becomes faster with breadboard-compatible pin headers, eliminating the need for a custom carrier PCB.
