40W motor driver has field-oriented management
A CPU is included and each sensor-less and sensor-based suggestions will be carried out.
“For purposes requiring flexibility in configuration, MLX81339 gives flash programmability,” mentioned the corporate. It “ensures dependable start-up, stopping and exact velocity management from low to most velocity”.
An internet based mostly device, ‘StartToRun’, is out there to generate configuration recordsdata and contains pre-filled mechanical worth recommendations.
Operation is throughout 6 to 26V and -40 to +125°C (150°C junction) – 40W is out there when equipped with 24V, dropping to 20W at 12V.
Inside, a 16bit CPU is backed by 32kbyte of flash and 2kbyte of ram – clocking will be at 24, 28, 32 or 36MHz.
Peripherals embody 5x 16bit motor PWMs, 2x 16bit timers, 1x 14bit timer and a <2µs ADC (13bit ±4A present, 12bit voltage and temperature).
Present output is configurable as much as 3A, and over-current safety is supplied alongside under-voltage, over-voltage and over-temperature safety.
Management will be through PWM, FG, I2C, UART or SPI, and there are eight general-purpose IO connections within the QFN24 packaged model – there’s additionally an easier SO8 model.
Industrial, business shopper and, by means of AEC-Q100 qualification, automotive appliclications are foreseen
