I have been using an IR3220S H-Bridge IC that has become obsolete. Is there any other ICs I could use since there is no replacements for it? My load is a motor that can draw about 5 amps and needs to be bi-directional.
I have been informed that the IR3220S H-Bridge MOSFET Driver IC has been obsoleted. There seems to be no drop-in replacement for it from International Rectifier. Is there any ICs out there that can perform similarily?
I am looking to redesign a 4-quadrant analog multiplier circuit that uses an obsolete IC, MLT04 from Analog Devices. Are there any circuits that can achieve this?
I am looking for a circuit to control a high current (40 amps) demagnetizer coil using the 60Hz line. We have used SCRs and high current diodes in the past that have become obsolete. The gate control circuitry for the SCRs is also outdated being designed with discrete transistors, etc. I would...
The PLC responds to 6 different inputs from various sensors with 4 outputs. We are controlling a motor's direction with a timed-out feature to avoid any overloading. Four of the inputs are limit sensors to control the motor's ON time. Two of the sensors are conditional that allow for the motor...
I am looking to create a logic circuit with no more than 20 gates. What would be better to use a PLD or PGA or something else? We are presently using a small PLC that is presenting alot of problems. Any more info would be appreciated. Thanks.
I want to use a 4N32 opto to drive a 5v relay coil (200 ohms) from a 24v source. Can I just divide down the 24v with a resistor tied from the 4N32 collector to the 24v and take the output from there with the 4N32 emitter to ground?
I would like to control the 60Hz AC power to a coil that will be used as a demagnetizer. I do not want to use a rheostat, but rather a state-of-the-art digital circuit that can be adjusted by an operator.
