... ACTIVE MAGNETIC BEARING • VIBRATION CANCELLING DESCRIPTION The SA50CE is a pulse width modulation amplifier that can continuously supply 5A to the load. The full bridge amplifier can be operated over a wide range of supply voltages. All of the drive/control circuitry for the lowside and high side switches are internal to the hybrid ...

... MTTF. For guidance, refer to the heatsink data sheet. 4. Guaranteed but not tested. 5. Derate linearly to 70V at – 40°C from T The SA50CE is constructed from MOSFET transistors. ESD handling procedures must be observed. CAUTION The internal substrate contains beryllia (BeO). Do not break the seal. If accidentally broken, do not crush, machine, or subject to temperatures in excess of 850° ...

... GND +12V ANALOG INPUT This is a diagram of a typical application of the SA50CE. The design Vcc voltage is +12 volts. V with a good low ESR ceramic capacitor. A higher ESR bulk capacitor, such as a tantalum electrolytic, may be used ex- ternally in parallel. The analog input can be an analog speed control voltage from a potentiometer, other analog circuitry or by microprocessor and a D/A converter ...
