A8290
Single LNB Supply and Control Voltage Regulator
Description (continued)
A comprehensive set of fault registers are provided, which comply
with all the common standards, including: overcurrent, thermal
shutdown, undervoltage, cable disconnect, power not good, and
tone detect.
Selection Guide
The device uses a 2-wire bidirectional serial interface, compatible
with the I 2 C? standard, that operates up to 400 kHz.
The A8290 is supplied in a lead (Pb) free 28-lead MLP/QFN.
