3 General Configuration and Description
3.1 Physical Access
Table 2 lists the TPS2482 and TPS2483 EVM connector functionality, and Table 3 describes the test point
availability.
Table 2. Table 2. Connector and Jumper Functionality
Connector Label Description
J1, J3 +IN, -IN Power bus input (high current screw down lugs). J1 is +IN and J3 is -IN.
J2, J4 +OUT, -OUT Switched bus output (high current screw down lugs). J2 is +OUT and J4 is –OUT.
USB Port. Connect furnished SM-USB-DIG and cable to PC when using the
J8 USB
TPS2482/3 GUI (see Figure 2).
Allows selection of the A1 I
2
C address bit. The EVM default is set to address 1000000.
J5 A1
For other address options, see the table in Figure 1.
Allows selection of the A0 I
2
C address bit. The EVM default is set to address
J6 A0
1000000.For other address options, see the table in Figure 1.
Sets the input voltage turn on point. Install a shunt on J7 for 9V UVLO and remove the
J7 UVLO
shunt for 18V UVLO.
Selecting the S1 EN position allows the TPS2482 and TPS2483 to enable the
S1 EN MOSFET if the power bus input is above the turn on voltage. Setting S1 away from
the EN position disables the MOSFET.
D5 (RED) ALERT Current monitor ALERT status.
Table 3. Test Points
Test Point Color Label Description
TP1 RED +IN Power bus input high.
TP4 BLK -IN Power bus input low.
TP3 ORG +OUT Switched bus output high.
TP5 BLK -OUT Switched bus output low.
TP2 WHT SNS SNS pin test point.
TP6 WHT GATE GATE pin test point.
TP7 WHT PG PG pin (power good) test point.
TP13 WHT TMR TMR pin (timer) test point.
TP15 WHT PRG PROG pin (power program) test point.
TP11 WHT EN EN pin (enable) test point.
TP10 WHT SCL SCL pin (serial clock) test point.
TP9 WHT SDA SDA pin (serial data) test point.
VS pin (current monitor supply voltage) test point. The USB
TP14 RED VS
source applied at J8 powers the current monitor.
GND pin (current monitor ground) test point. The USB source
TP8 BLK GND
applied at J8 powers the current monitor.
TP12 WHT ALERT Current monitor ALERT pin.
