Self-powered BridgeSwitch half-bridge motor driver ICs dramatically simplify the development of high-voltage single- or multi-phase BLDC motor drives.

モーターが組み込まれた家電製品は、国際的な安全基準で規定された特定の要件に準拠することが求められます。統合型ハーフブリッジ アーキテクチャの BridgeSwitch は、フェイルセーフで冗長化した独自のローサイド及びハイサイドサイクル・バイ・サイクルのカレントリミット機能を有します。これにより、異常動作時のモーターの保護をその保護のためのソフトウエアに依存することなく、保護装置として機能させることが可能です。このソフトウエアに依存せずにモーターを保護することにより、安全基準認証プロセスを大幅に簡素化及び短縮することを可能にします。

Power Integrationsの製品マーケティングマネージャーであるEdward Ongは、CAPZero-2集積回路を使用して、IEC 62368-1の最新の安全要件を満たしながらアイドル損失を削減する方法を説明しています。

High performance motor drives commonly use field-oriented control (FOC) since it offers smooth and efficient operation throughout the entire speed range. BridgeSwitch offers a unique function by providing a small signal output that is an instantaneous representation of the positive phase current. This function can eliminate commonly used discrete current

BridgeSwitch allows building compact, high-voltage brushless DC motors drives without having to use a physical heatsink. This document discusses techniques for optimizing the PCB layout, including device arrangement, inter device distance, and copper clad area, all of which play an important role in the thermal performance of the device.

The efficiency and size benefits of SiC devices have been enthusiastically embraced by designers of industrial, automotive, traction systems and photovoltaic power conversion. To provide more detail, the lower sheet resistance of wide-bandgap SiC materials (typically 1/100th that of conventional silicon) results in smaller devices for a given current capacity—valuable

During PCIM Europe 2025 in Nuremberg, Juan Paolo Quismundo gave a oral presentation on how to maximize available power to display, controls and communications functions for appliances needing to comply with increasingly stringent standby energy regulations. Our BridgeSwitch motor driver ICs, combined with the MotorXpert software suite, allow sleep-mode power

Integrating current sensing into the low-side switch enhances system efficiency and simplifies predictive maintenance for three-phase motors.

During PCIM Europe 2025 in Nuremberg, John Emmanuel Tan gave a poster presentation introducing a single-phase BLDC motor design for external fan applications. Our BridgeSwitch motor driver ICs, combined with the MotorXpert software suite, support a power range of 30 W to 746 W (1 HP) and deliver inverter efficiency up to 99%. 

During PCIM Europe 2025 in Nuremberg, Juan Paolo Quismundo gave a poster presentation on how to enable field-oriented control (FOC) without shunts and sensing circuits. Our BridgeSwitch motor driver ICs, combined with the MotorXpert software suite, support a power range of 30 W to 746 W (1 HP) and deliver inverter efficiency up to 99%.
