UTC 51494
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.
