SINGLE LNB-BIAS, CONTROL AND POWER MANAGEMENT SOLUTION

DESCRIPTION

The UTC L8200/A is a single chip power management and
control solution for LNB’s. The highly integrated solution provides
all the required FET and mixer bias, control detection and
decoding, local oscillator switching and a stable power supply for
the IF amplifier, and additional support functions. Packaged in a
small 16 pin QFN package or 16 pin TSSOP package the UTC
L8200/A only requires 3 external components providing a very
small compact solution. Being at the heart of the LNB monitoring
the control, power management and environmental conditions the
UTC L8200/A is able to provide reliable solution eliminating
effects such as false switching and over loading.
UTC L8200 polarization switching threshold is 14.1V~15.4V
and UTC L8200A switching polarization threshold is 14V~14.5V.
