DESCRIPTION
LINEAR INTEGRATED CIRCUIT
The UTC 51494 is a monolithic bipolar integrate circuit that provides both 494 function and built in power good signal circuit for easy using 51494 can be easily implemented by just adding a capacitor.
FEATURES
*Fully integrated with compact 16-pin dip *All necessary functions included for most popular half bridge circuit. *Built-in power good delay and power fail lead function. *Power good delay time is linearly. *Proportional to external capacitor value. *Reduced external components for cost down and components for cost down and compact size.
