Phase Control Circuit - General Purpose Feedback
Description
The integrated circuit U211B2/ B3 is designed as a phase
control circuit in bipolar technology with an internal fre-
quency-voltage converter. Furthermore, it has an internal
control amplifier which means it can be used for speed-
regulated motor applications.
Features
It has an integrated load limitation, tacho monitoring and
soft-start functions, etc. to realize sophisticated motor
control systems.
Internal frequency-to-voltage converter
Externally-controlled integrated amplifier
Overload limitation with a “fold back” characteristic
Optimized soft-start function
Tacho monitoring for shorted and open loop
Automatic retriggering switchable
Triggering pulse typ. 155 mA
Voltage and current synchronization
Internal supply-voltage monitoring
Temperature reference source
Current requirement
3 mA
