AM4961AGHTR-G1

Overview

The AM4961AGHTR-G1 is a single-phase brushless DC motor controller manufactured by Diodes Incorporated. It operates within a supply voltage range of up to 12 V and supports an output voltage of 18 V with a maximum output current of 1 A. The device functions at a working frequency of 25 kHz and dissipates power up to 1.1 W. It is housed in a 14-HTSSOP package suitable for surface mount installation. The component operates reliably across a temperature range from -30°C to +90°C, with a quiescent current consumption specified between 8 mA and 15 mA.

Feature Summary

• Integrates full control and power stages for single-phase BLDC motor applications
• Supports PWM interface for precise motor speed and direction control
• Designed for efficient operation with low quiescent current consumption

Applications

• Single-phase brushless DC motor control systems
• Fan and pump speed regulation circuits
• Industrial motion control modules

Procurement Notes

Verify the current lifecycle status before procurement as official notifications indicate potential end-of-life discontinuance. Confirm moisture sensitivity level (MSL 3) requirements for storage and handling procedures. Ensure compatibility with the 14-HTSSOP footprint during PCB layout finalization. Validate that the 12 V maximum supply voltage aligns with system power rails.

Selection Notes

Select this component for designs requiring integrated single-phase BLDC driving capabilities without external power transistors. Consider the 1 A output limit and 1.1 W power dissipation when designing thermal management solutions. Verify that the 25 kHz operating frequency meets noise and efficiency constraints. Ensure the HTSSOP-14 package fits within the available board space constraints.
