A8293
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, and power not good.
The device uses a 2-wire bidirectional serial interface, compatible
with the I2C™ standard, that operates up to 400 kHz.
The A8293 is supplied in two lead (Pb) free MLP/QFN packages:
ES, 20-contact, 4 mm × 4 mm, 0.75 nominal overall height, and
ET, 28-contact, 5 mm × 5 mm, 0.90 nominal overall height.
