Calculating Required Resistor Values in the Circuit
To determine the proper resistor values for the IC 24X reference circuit under high voltage conditions, start by identifying the desired current flowing through each component. Select the target current based on the specifications of your circuit and the rated performance of the IC. Use Ohm’s Law (V = I × R) to calculate the resistor value, where V represents the voltage drop across the resistor, I is the target current, and R is the resistance value.
Next, assess the supply voltage and reference voltage needed for operation. Subtract the reference voltage from the supply voltage to find the voltage drop required across each resistor. Once you have the voltage drop, rearranging Ohm’s Law will yield the necessary resistance values. For instance, if your supply voltage is 12V, the reference voltage is 5V, and the target current is 10mA, the resistor value would be calculated as:
R = (V_supply – V_reference) / I_target
R = (12V – 5V) / 0.01A

Consider the power rating of the resistor as well. Use the power formula (P = I² × R) to ensure the resistor can safely dissipate the heat generated. For the previous example with a resistor value of 700Ω at 10mA, calculate:
P = 0.01A × 0.01A × 700Ω
P = 0.07W
Select a resistor with a power rating higher than this value, typically a ¼ watt resistor would suffice. Ensure component tolerances are taken into account by opting for resistors with a tighter tolerance for accuracy, especially in critical applications.
When configuring multiple resistors in series or parallel, adjust the calculations accordingly. In series, simply sum the resistor values. In parallel, use the formula:
1/R_total = 1/R1 + 1/R2 + …
Finally, always prototype your circuit to validate theoretical calculations against practical results, ensuring the performance meets the design specifications under actual operational conditions.
