Features

are programmable via the device’s SPI port. Load current is continuously sampled and compared to the programmable 7−bit peak/hold DAC values while the load self−modulates to maintain the desired currents at each of the peak and hold points. Passive fault diagnostics monitor and protect the MOSFETs when a fault is detected. Fault data is available via SPI and an open−drain FAULT output provides immediate fault notification to a host controller. The FlexMOS family of products offers application scalability through choice of external MOSFETs. Features http://onsemi.com MARKING DIAGRAM 20 20 1 SO−.
