Description and Introduction

DMOS Full-Bridge Motor Driver The **A3949SLPTR-T** is a high-performance, fully integrated **MOSFET driver** designed for automotive and industrial applications. This component is specifically engineered to drive **N-channel power MOSFETs** in **half-bridge configurations**, making it ideal for motor control, solenoid actuation, and other power-switching applications.  

Featuring **low-side and high-side gate drivers**, the A3949SLPTR-T provides robust performance with **adaptive dead-time control**, preventing shoot-through currents and enhancing system reliability. Its **wide operating voltage range (up to 50V)** ensures compatibility with various power supply conditions, while integrated **bootstrap diode functionality** simplifies circuit design.  

The device includes **thermal shutdown** and **undervoltage lockout (UVLO)** protection, safeguarding against fault conditions. Additionally, its **high noise immunity** makes it suitable for harsh environments, such as automotive systems where electromagnetic interference (EMI) is a concern.  

Available in a **small TSSOP-16 package**, the A3949SLPTR-T offers a compact solution for space-constrained designs. Its **low-power standby mode** further enhances energy efficiency, making it a versatile choice for power management applications.  

With its **high current drive capability** and **advanced protection features**, the A3949SLPTR-T is a reliable solution for demanding motor control and power-switching applications.
