KV Series Arm Cortex-M4/M0+/M7


  • Input and output voltage sensing with under and over voltage protection transformer primary current sensing with over load and short circuit protection.
  • Full-bridge MOSFET driver to driver primary full bridge MOSFETs and half-bridge MOSFET driver for synchronous MOSFET driving.
  • Power supply input voltage input of 20-30 V DC, output voltage 5 V and load up to 8 A.
  • Dynamic/transient load circuit to test digital control loop performance on transient load.
  • Operates over supply voltage range of 4.5 V < VPWR < 36 V
  • Start-up/shut-down control and power sequence logic with KEYSW input
  • MCU supply: VCC is a 5.0 V (±2.0%, 200 mA) regulated supply
  • Sensor supply: VPROT (100 mA) is a VCC tracking protected sensor supply
  • Two configurable pre-drivers for IGBT or general purpose gate MOSFETs for ignition and O2 sensor (HEGO) heater
  • PWM
