AM4961GHTR-E1

Overview

The AM4961GHTR-E1 is a single-phase full-wave direct PWM motor driver manufactured by Diodes Incorporated. It integrates high-side and low-side MOSFET drivers with an integrated bootstrap diode for efficient gate drive management. The device supports direct pulse-width modulation input signals to control motor speed and direction without external logic. Designed for robust operation, it features built-in protection mechanisms including over-current protection, under-voltage lockout, and thermal shutdown to ensure system reliability during continuous duty cycles.

Feature Summary

• Integrates high-side and low-side MOSFET drivers with an internal bootstrap diode
• Supports direct PWM input signal control for simplified interface design
• Includes comprehensive protection features such as over-current, UVLO, and thermal shutdown

Applications

• Single-phase DC motor speed control systems
• Fan and pump motor driver circuits
• Small appliance motor control applications

Procurement Notes

Verify the exact suffix against official Diodes Incorporated documentation to confirm package type and tape/reel specifications. Confirm current availability status as distribution channels may list obsolete or discontinued inventory. Ensure compatibility with existing PCB footprint and thermal requirements before finalizing procurement orders.

Selection Notes

Select this component for applications requiring a compact solution for single-phase motor control with integrated power stage capabilities. Evaluate thermal performance constraints relative to the TSSOP-14 package limitations. Consider the direct PWM interface requirement to determine if additional logic buffering is necessary for the specific microcontroller output levels.
