GENERAL DESCRIPTION
(Continued)
One unique feature of the ML6509 is its support for a Low
Power mode, for use in Notebook and portable computer
applications, where it provides a 1mA (approximately
2.5K
termination) for less than 6" cable lengths. This
minimizes the battery drain significantly in such systems.
Current limiting and thermal shutdown protection are also
provided. The nine line configuration is optimal for wide
SCSI’s 18, 27, or 45 line termination needs.
NOTE :
The
DISCNKT
and
LPWR
lines have 200ky internal pullup resistors
connected to the supply. These pins should be left floating for normal
operation and should be connected to ground to enable the function.

TERMPWR
Termination Power. Should be connected
to the SCSI TERMPWR line. A 10μF
tantalum local bypass capacitor is
recommended per system, as shown in

2.85V
REF
Output. External decoupling
with a 10μF tantalum in parallel with a
0.1μF ceramic capacitor is
recommended, as shown in the
application diagram.
DISCNKT
Disconnect Terminator. Logic input to
disconnect the terminator from the bus
when the SCSI device no longer needs
termination due to not being the last
device on the bus or otherwise. Active
low input.
LPWR
Low Power Mode. Logic input to switch
the terminator mode to a ~2.5k
termination, with a 1mA drive capability,
meant for power conscious battery
applications which use SCSI devices
supporting cable lengths less than six
inches. Active low input.
GND
HS
Ground. Signal Ground (0V)
Heat Sink Ground. Should be connected
to GND.
