Power Integrations unveils their new motor control solution
In this video friend of the show Andy Smith of Power Integrations talks to Alix Paultre from Aspencore Media about their new BridgeSwitch ICs, which feature high- and low-side advanced FREDFETs (Fast Recovery Diode Field Effect Transistors) with integrated lossless current sensing, resulting in inverter conversion efficiency of up to 98.5% in brushless DC (BLDC) motor drive applications to 300 W.
The 600 V FREDFETs used in BridgeSwitch ICs incorporate fast, ultra-soft-recovery body-diodes. This drastically reduces losses during switching and reduces noise generation, which simplifies system level EMC. The new high-voltage, self-powered, half-bridge motor driver ICs also feature built-in device protection and system monitoring and a robust single-wire status update interface which enables communication between the motor-microcontroller and up to three BridgeSwitch devices.

Combining security with advanced process nodes has become a challenge in recent years. This is due to the diminishing alternatives for embedded flash when moving past the 28nm process node. Winbond has introduced the TrustMe secure flash products to address this challenge and remove the barriers for adding secure non-volatile storage to practically any process node out there.
Even though NOR flash remains attractive for code storage it has reached its technology limit. The solution is Serial SLC NAND flash based on the SPI interface, offering a better cost per bit with significant compatibility to serial NOR.
More and more real time applications do require a very strong CPU capability, aside integrated peripherals. But, there was still a question mark with regards to the amount of embedded flash needed in these applications. The new value lines STM32 microcontrollers will ease this decision process and give more flexibility to the developers.
Software vulnerabilities can manifest themselves in many ways, but typically, they are exploited by abusing software interfaces in ways outside of their designed operation. But we can help ourselves during our development to make static analysis tools more accurate and relevant to our cause.
