Description
Each device in the family handles an overcurrent event differently depending on the option selected. The MAX14575A/MAX14575AL feature an autoretry mode; the MAX14575A has active-high EN polarity, while the MAX14575AL has active-low EN polarity. The MAX14575B has latch-off mode, and the MAX14575C features a continuous current-limit mode. Additional safety features include thermal-shutdown protection to prevent overheating and reverse-current blocking to prevent current from being driven back into the source.
The MAX14575A/MAX14575AL/MAX14575B/MAX14575C are available in a small 2mm x 2mm, 8-pin TDFN package and operate over the -40°C to +85°C extended temperature range.
