NOTE:

▪ All of the input pins are connected to GND with internal pull-down resistors rated at 100 kΩ, however, an external pull-down

resistor may be required to secure stable condition of the inputs if high impedance conditions are applied to them.

▪ To use the OCP circuit, an external shunt resistor, RS, is needed. The RS value can be obtained from the formula:

.

▪ A blanking timer is built-in to mask the noise generated on RS at turn-on.

▪ The external electrolytic capacitors should be placed as close to the IC as possible, in order to avoid malfunctions from

external noise interference. Put a ceramic capacitor in parallel with the electrolytic capacitor if further reduction of noise

susceptibility is necessary.
