V
— Connect to a second Power Supply 5V
(or 3.3V) connection – V
provides the pull-up
voltage for Enables ENA & ENB and Flags
FLGA & FLGB. This separate supply connection
allows the user to separately measure V
IN
supply
current.
GND — Second Power Supply GND Connection –
connect to supply return for V
DD
.
ENA — U1-1 —Enable A Input must be
connected High or Low – open produces
unstable behavior, so be sure to connect V
to
an external 3.3V or 5V source. See
Table 1
Enable Jumpers for information on Enable
Jumper J1 position. The user can actively
control Switch A with an external Logic signal.
FLGA — U1-2 — Flag A output is open drain
and has a pull-up to V
(which should be
connected to an external source). Connect
FLGA to voltmeter or oscilloscope to monitor
Switch A for flags when Low if Under-voltage,
Over-current or Over-temperature occurs.
.
ENB — U1-4 — Enable B Input must be
connected High or Low – open produces
unstable behavior, so be sure to connect V
to an external 3.3V or 5V source. See
Table 1
Enable Jumpers for information on Enable
Jumper J2 position. The user can actively
control Switch B with an external Logic signal.
FLGB — U1-3 — Flag B output is open drain
and has a pull-up to V
(which should be
connected to an external source). Connect
FLGB to voltmeter or oscilloscope to monitor
Switch B for flags when Low if Under-voltage,
Over-current or Over-temperature occurs.
Using the Enable Jumbers J1 & J2
The jumpers J1& J2 have 2 positions, as
described below. Connecting a logic level to
the ENA or ENB test point post will override
the pull-up or pull-down to actively control
the switch.
