The combination of STM32F0 microcontroller and high-voltage driver enabling direct control of executive transistors creates a flexible platform for a wide spectrum of power-diverse applications.

The combination of STM32F0 microcontroller and high-voltage driver enabling direct control of executive transistors creates a flexible platform for a wide spectrum of power-diverse applications.
Each of the controllers from the STSPIN32F025x or STSPIN32F060X family contains of the uC connection STM32F031, a three-phase high-voltage driver, a built-in bootstrap diode and also includes a comparator for programmable overcurrent protection. The driver is adapted to work with N channel MOSFET or IGBT transistors. Two versions of the driver’s current efficiency are available: IGATE = 0,2A oraz IGATE = 1A.

All these elements are placed in a compact 10 x 10mm housing and can operate in the temperature range from -40 to +125 ° C.

The manufacturer provides hardware support in the form of a wide selection of evaluation boards and software facilities fully compatible with the STM32 ecosystem, including tools for determining engine parameters.
