I have a question about the enable pins for the ISL32172EFVZ chip. Page 14 shows if we need to enable the outputs, we need to put EN = 1 or /EN = 0. To disable, otherwise.
However, page 4 shows this table. Does this table indicate that if EN = 1, it only activates one output? Could you explain the table to me in a bit more detail? Because we need to have all outputs activated
The ISL32172 uses the EN (active HIGH) and /EN (active LOW) pins to control the enable/disable state of its Tx outputs. As clearly stated, to enable the outputs, you must ensure that EN = 1 and /EN = 0. These two pins act together to control all the driver outputs simultaneously—there is no separate or independent enablement of individual outputs in this device.
If you need to enable all outputs, the correct configuration is to set EN = 1 and /EN = 0. If EN = 0 or /EN = 1, the outputs will be disabled. Therefore, for the ISL32172, the EN and /EN pins globally control all outputs, and no partial enabling of outputs is possible.
