Using uPC1237 for over current protection allows the designer to drop the SOA limiting elements in the power amplifier. This will save space on the PCB, lower the cost of the project and
DESCRIPTION UTC UPC1237 is a semiconductor integrated circuit designed for protecting stereo power amplifiers and loudspeakers.
Directly connecting pin ③ to the ground is the automatic reset working mode, that is, after the protection circuit operates and the relay disconnects the speaker, if the power amplifier circuit
A sophisticated and well-designed protection system can reduce the cost of the output transistors, the size of the heat sinks. In modern models there are many output transistors and there
PROTECTOR IC FOR STEREO POWER AMPLIFIER DESCRIPTION uPC1237 is a monolithic integrated circuit designed for protecting stereo power amplifiers and loudspeakers.
UTC UPC1237 is a semiconductor integrated circuit designed for protecting stereo power amplifiers and loudspeakers. FEATURES * Wide supply voltage range of 25V~60V * Contain a relay
Use it as intended, so 24V minimum. As the suggested schematic clearly says: In fact, this schematic uses TWO 12V relays, connected in series. Just curious: do you have a 12V powered
If the IC detects the abnormal condition such as the larger output offset level or the overload, the IC can make the relay broken OFF. And then, two functions can be selected after the condition returns to
Unisonic Technologies is a Taiwanese semiconductor company that specializes in the design, manufacture, and sales of power management and analog integrated
Once the positive or negative offset voltage of the output terminal of the power amplifier exceeds the set threshold, the internal circuit of uPC1237 releases the relay and disconnects the
This internal circuit controls the relay to disconnect the amplifier output from the speakers, preventing any impact noise during the transition when the power output is at zero level.
UTC UPC1237 is a semiconductor integrated circuit designed for protecting stereo power amplifiers and loudspeakers. FEATURES. * Wide supply voltage range of 25V~60V. * Contain a relay driver. (Max.
DESCRIPTION UTC UPC1237 is a semiconductor integrated circuit designed for protecting stereo power amplifiers and loudspeakers. FEATURES * Wide supply voltage range of 25V~60V. * Contain
