MAX16545BGPF+T: FAQ

Question: For overcurrent warning (if enabled by PMBus), will it reflect on /FAULT pin? Or it only reflects on the register bit after triggered? Answer: It will not assert /FAULT output and only set…

In the MAX16545B, the OVP protection is disabled by default and cannot be enabled through PMBus. However, the PWRGD signal is de-asserted when the input rises above the 16V OVP threshold.

In the MAX16545B, the OVP protection is disabled by default and cannot be enabled through PMBus. However, the PWRGD signal is de-asserted when the input rises above the 16V OVP threshold.

Question: For Moderate OCP setting, could it be overwritten by PMBus? Answer: Yes, OCP setting can be overwriten on register via PMBus.

The ILOAD output circuit is “powered” from the VDD rail (internal LDO), even though you might expect a high output current transient to drive a high current out of the ILOAD pin, the practical result is…

We do not recommend using TVS this way. During layout, we advise the TVS to be placed as closer to chip as possible. For the parallel, we cannot make sure different HotSwaps are placed very close or not…

The ADC in the MAX16545B saturates at 13.5V and cannot convert any values above this.

The ADC in the MAX16545B saturates at 13.5V and cannot convert any values above this.

Answer: Essentially, the EC Table specified operating range is 12V ±10% because the part is targeted for applications with 12V system rails. This explains why the 10.8V to 13.2V range in the datasheet…
