PMSM FOC design, tiny USB-C protection ICs, high-precision dual op amp, zero-power standby SMPS and more – 09 March 2017

Jump start your FOC BLDC motor design with new firmware example

The STSW-SPIN3201 is a firmware example based on the STM32 PMSM FOC SDK (STSW-STM32100) for the 32-bit MCU-based STSPIN32F0 motor driver, which features the flexibility and power of an MCU-based motor drive with the convenience and space-efficiency of a single IC. With the STEVAL-SPIN3201 evaluation board, it allows to control a 3-phase PMSM with field-oriented control algorithms in sensorless mode. It enables fast prototyping of smart-manufacturing equipment, drones, and high-performance home appliances.


Industry’s smallest power-dense ESD & EOS protection ICs for USB Type-C ports

ST extends its dedicated 30-kV protection series for USB charging circuits with five new transient voltage suppressors. The ESDAxP series – designed with the best clamping ratio for 5 to 20 V USB-powered devices – provides the best-in-class surge current protection capability within the tiniest possible package (1.6 x 1.0 mm), and improves the whole circuit lifetime. The ESD robustness of the entire TVS series goes well beyond the IEC 61000-4-2 Level 4 specification.


Zero-power standby SMPS with remote-control wake-up

Based on the VIPer0P 800 V avalanche-rugged high-voltage converter with zero-power standby, the STEVAL-ISA181V1 is a remote-controlled 12 V / 600 mA isolated flyback SMPS with a smart standby architecture featuring zero-power mode (ZPM). In ZPM idle state, power consumption is below 5 mW. The ZPM combined with the IR remote on/off control makes it ideal for air conditioning systems.


Need very high-precision in a tiny package? ST makes it possible

The TSZ182 dual op amp is a 5 V chopper-stabilized op amp with a 3 MHz gain bandwidth, rail-to-rail inputs and outputs, and ultra-small 2 x 2 mm DFN8 or Mini-SO8 packages. The offset voltage of 25 µV at 25°C enables high measurement resolution and precision. These features make the TSZ182 ideal for high-accuracy high-bandwidth sensor interfaces like body-signal monitors, blood-glucose meters, industrial sensors, factory automation, automotive applications and low-side current sensing.


I2PAKFP package extends 950 V MDmesh K5 MOSFET portfolio

Ideal for compact and slim designs such as LED driver applications and slim laptop adapters, the 950 V, 0.50 Ω (max) RDS(on) STFI15N95K5 is housed in the fully-molded I2PAKFP through-hole package (JEDEC-approved TO-281) which is 30% shorter than the TO-220FP, yet shows the same thermal performance and electrical isolation. In slim designs, the package can be mounted above the standoff height, which improves the overall reliability
