Piccolo - Small Servo Amplifiers

The PICCOLO series of miniature servo amplifiers for brushless DC Motors is designed for motion systems where the motor's trapezoidal commutation is performed by the amplifier. The PICCOLO is a trimmerless design for the OEM market and may be mounted directly on the customers PC board as a component. The product meets UL 508c and the relevant CE regulations.

The power stage is implemented on a single ceramic substrate. This design enables very high thermal conductivity, high current carrying capacity, better EMC and good mechanical strength. The control section is implemented by dedicated custom ICs that contribute to higher reliability because fewer components are used and improved performance due to the high level of integration.

Features:

• Operation in current mode
• Internal DC to DC converter enables operation from one single supply
• Two differential command reference inputs
• Zero deadband
• Excellent linearity
• External continuous and peak current limit adjustments
• Current feedback multiplier for low current motors
• Remote current gain control
• Enable input
• 3 motor current monitors
• Status indication by 4 open collector opto couplers
• Latch mode of the protective functions
• Ultra-compact size
• Interface via solder pins
• Package: Plated copper base plate, plastic housing, UL94V0 recognized
