简  介:Features Internal Frequency-to-voltage Converter Externally Controlled Integrated Amplifier Overload Limitation with “Fold Back” Characteristic Optimized Soft-start Function Tacho Monitoring for Shorted and Open Loop Automatic Retriggering Switchable Triggering Pulse Typically 155 mA Voltage and Current Synchronization Internal Supply-voltage Monitoring Temperature Reference Source Current Requirement ≤3 mA 1. Description The integrated circuit U211B is designed as a phase-control circuit in bipolar technology with an internal frequency-to-voltage converter. The device includes an internal control amplifier which means it can be used for speed-regulated motor applications. Amongst others, the device features integrated load limitation, tacho monitoring and soft-start functions, to realize sophisticated motor control systems. Figure 1-1.
