U2350B-FP
PWM Speed Control for Permanent Excited DC Motors
Description
The monolithic integrated bipolar circuit U2350B is a
MOSFET or IGBT - control circuit which works on the
principle of pulse width modulation (PWM). The overall
concept enables the construction of a power controller
with mains voltage compensation where intermittent
operation is also possible. In addition, the circuit also
enables mains-voltage compensated current control,
which maintains the power supplied at a constant level
after the preset threshold has been exceeded.
Features
D Pulse width control up to 30 kHz clock frequency
D Mains supply compensation
D Current regulation
D Temperature monitoring with indicator
D Active operation indicator
D Blink-warn indicator
D Switchable to interval operation
D Push-pull output stage for separate supply
