Test
Test Output
This pin must be grounded in the application.
12
RTNOUT
Power
Bus Return
Switched RTNIN pin, attaches to the next RTNIN pin in the daisy chain.
13
RTNIN
Power
Bus Return
Pin attaches to the low side of the differential bus, and provides the common
return for power and signalling. It is internally connected to AGND.
14
BUSOUT
Output
DBUS Output
Switched BUSIN Pin, attaches to the next BUSIN pin in the daisy chain.
15
BUSIN
Input
DBUS Input
Pin attaches to the high side of the differential bus and responds to
initialization commands.
16
H_CAP
Output
Holding
Capacitor
A capacitor attached to this pin is charged by the bus during bus idle and
supplies current to run the device and for external devices via the REGOUT
pin during non-idle periods.
