T8094 is a monolithic H‑bridge DC motor driver IC. It integrates power MOSFETs, control logic, and protection circuits into a single chip, enabling bidirectional drive, PWM speed control, and dynamic braking for small‑to‑medium brushed DC motors. It is widely used in consumer electronics, smart home devices, office equipment, and battery‑powered motor systems.

Features

Integrated H‑bridge structure supports bidirectional rotation and electric brake.
Wide operating voltage range: 6V to 24V, compatible with 12V/24V motor systems.
High output current capability: continuous up to 3A, peak up to 5A.
Built‑in PWM generator for adjustable speed via duty cycle control.
Logic inputs are CMOS/TTL compatible, allowing direct connection to MCU or logic circuits.
Integrated over‑current, over‑temperature, and under‑voltage protection.
Low on‑resistance minimizes power dissipation and heat generation.
Available in compact SOP‑16 package for easy surface mounting.
