I would like to ask you some questions about LM5069,
1.If the LM5069 power supply and ground connection are reversed, will the chip be damaged?
2.As for the power limiting function, the VSNS voltage of the chip is recommended to be no less than 5mV (the sampling resistance is selected at 1mΩ, the maximum output current is 55A, so the minimum current is 5A when starting the MOS power limiting function). Since our input voltage is up to 60V, if the current is 5A, it is not less than 5mV. The maximum power received by mos will reach 60X5=300W, the stress on MOS is still too large, so a smaller current is needed to pass through MOS at this time, can I use a smaller VSNS voltage value? According to the specification, when VSNS is less than 5mV, the current sampling accuracy is not high, is there a more definite value for this accuracy?
3.After the chip is started, the maximum current set by our chip is 55A. Can the chip work normally when the load current is less than 55A (such as 45A)?
