LINEAR INTEGRATED CIRCUIT
DESCRIPTION
The UTC 51494 is a monolithic bipolar integrate circuit that
provides same 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.
