L8200L8200A数据手册UTC中文资料规格书

描述 Description

The UTC L8200/A is a single chip power management andcontrol solution for LNB’s. The highly integrated solution providesall the required FET and mixer bias, control detection anddecoding, local oscillator switching and a stable power supply forthe IF amplifier, and additional support functions. Packaged in asmall 16 pin QFN package or 16 pin TSSOP package the UTCL8200/A only requires 3 external components providing a verysmall compact solution. Being at the heart of the LNB monitoringthe control, power management and environmental conditions theUTC L8200/A is able to provide reliable solution eliminatingeffects such as false switching and over loading.UTC L8200 polarization switching threshold is 14.1V~15.4Vand UTC L8200A switching polarization threshold is 14V~14.5V.
