WT8048 Datasheet | Weltrend Semiconductor

DESCRIPTION The WT8048 is a 8 pin P-DIP package IC, designed for the application of Power Saving Monitor or Green Monitor. As per DPMS proposal, the WT8048 provides a detective circuit of monitor power management for the convenience of designers in designing Power Saving Monitor. FEATURES { Accepting two seperated H&V synchronous signals with positive/ negative polarity. { Capable of processing horizontal frequency between 0Hz to 100k Hz, and vertical frequency between 0Hz to 100Hz. { Power Saving mode - It can detect the conditions of monitor to decide which will be selected as following: ON mode / STAND_BY mode / SUSPEND mode / OFF mode. { An Override mode is defined to override the DPMS function during the design, test, burn-in manufacture or diagnostic process if desired. APPLICATION { DPMS mode's detection for Green Monitor Weltrend Semiconductor, Inc. 2F., No. 24, Ind. E. 9th Rd., Science-Based Ind. Park, Hsin-Chu, Taiwan, R. O. C.
