Power Integrations Brushless DC Motor and AC Motor Driver IC 24-Pin Surface Mount InSOP-C Package BRD1265C-TL

Power Integrations BRD1265C-TL is a brushless DC motor and AC motor driver integrated circuit designed for efficient and compact motor control solutions. This device integrates a fully integrated half-bridge stage with achievable efficiency up to 98 percent, eliminating the need for external heat sinks under normal RMS current conditions. It features 600 V N-channel power FREDFETs combined with ultra-soft, fast recovery diodes to provide highly reliable and efficient switching performance.

The IC provides precise instantaneous phase current information output, simplifying system design by removing the necessity for external sensing and amplification circuitry. Its self-biased low-side and high-side drivers eliminate auxiliary power supply requirements. The compact 24-pin InSOP-C surface mount package includes exposed pads enabling effective PCB heat sinking.

Designed for robust usage, the BRD1265C-TL features adjustable cycle-by-cycle current limiting for both FREDFETs and dual-level thermal overload protection. It includes multiple protections such as fail-safe operation, system-level monitoring inputs, and protections against undervoltage, overvoltage, and overtemperature conditions. The controlled FREDFET switching speed helps reduce electromagnetic interference.

This motor driver IC supports 2- and 3-phase high-voltage permanent magnet and brushless DC motor drive applications with inverter output power typically up to 300 W in domestic appliances like dishwashers and refrigerators, as well as condenser fans for energy-efficient air conditioners and other industrial and commercial motor control applications.

The device has a maximum supply voltage rating of 50 V and typical supply current of 12 mA. Operating temperature range spans from -40°C to 150°C for wide environmental tolerance. It conforms to no specific automotive standards and includes no certifications or approvals.

Pin count is 24 with package dimensions approximately 9.4 mm length, 10.8 mm width, and 1.45 mm height. Adjustable dead time and simultaneous conduction lockout enhance system reliability and performance.

The Power Integrations BRD1265C-TL Motor Driver IC offers a high-performance, flexible, and integrated solution for reliable motor control in industrial, commercial, and household settings. This product creates opportunities for compact PCB designs needing thermally efficient, precise motor drive control.
