The UTC
UR5516
is designed to provide a regulated voltage with
bi-directional output current for DDR-SDRAM termination.
Current-limit work to limit the short-circuit current, on-chip thermal
shutdown provides protection against any combination of overload
that would create excessive junction temperature. The output voltage
tracks the voltage at V
REF
pin. A resistor divider connected to V
IN
,
GND and V
REF
pins is used to provide a half voltage of V
IN
to V
REF
pin. In addition, an external ceramic capacitor and an open-drain
transistor connected to V
REF
pin provides soft-start and shutdown
control respectively. Pulling and holding the V
REF
to GND shuts off
the output. The output of UTC
UR5516
will be high impedance after
being shut down by V
REF
or thermal shutdown function.
