U209B-XFP

The U209B-XFP is designed as one kind of low-cost phase-control IC that includes an internal open-loop amplifier, which means it can be used for motor speed control with tacho feedback. Also this device is a 14-pin shrink version of the U211B with reduced features. Using the U209B, the designer is able to realize sophisticated as well as economic motor control systems.

Features of the U209B-XFP are:(1)Internal Frequency-to-voltage Converter; (2)Externally Controlled Integrated Amplifier; (3)Automatic Soft Start with Minimized "Dead Time"; (4)Voltage and Current Synchronization; (5)Retriggering; (6)Triggering Pulse Typically 155 mA; (7)Internal Supply-voltage Monitoring; (8)Temperature-compensated Reference Source; (9)Current Requirement </=3 mA.

The absolute maximum ratings of the U209B-XFP can be summarized as:(1)Current limitation Pin 5 t 10 s: 30 mA or 100 mA;(2)Synchronous currents Pin 7 t 10 s: 5 mA;(3)Ambient temperature range: -10 to +100 °C;(4)Input current: 500 uA;(5)Charge current Pin 6: 0.5 mA;(6)Input voltage: -VS to +2 V;(7)Input voltage Pin 8: 2 to Vs V;(8)Storage temperature range: -40 to +125 °C;(9)Junction temperature range: +125 °C.
