AN5765
CRT heater voltage control IC
■ Overview
The AN5765 is an IC for CRT heater voltage control.
The incorporation of 4 values of heater voltage changeover output circuit, 5 V power supply and reset circuit for
microcomputer, and the adoption of SIP 7-pin package
with fin can realize the rationalization and power saving
of the set.
■ Features
• Incorporating 4 values changeover output circuit
• Incorporating 5 V constant voltage output
• Incorporating reset function
• Incorporating current protection and thermal protection
circuit
■ Applications
• CRT monitors
