4 Connection Descriptions

Most connectors and test points are labeled with their functional names on the silk screen of the PCB and the actual component names are omitted to avoid clutter on the silk screen of the EVM. Likewise, jumpers are labeled to be self explanatory. Table 4-1and Table 4-2 contain a description of each test point and its purpose.

Note that by default the TPS1HC100EVM comes configured for standalone operation with no attached LaunchPad.

(supply)

J6, J8, GND test pointsGround connection (system ground)
DIAG_ENEnable and disable diagnostics on the TPS1HC100B-Q1
ENEnable line for the TPS1HC100B-Q1
LATCHControls latch functionality for the TPS1HC100B-Q1
SNSCurrent sense test point for the current sense output of the TPS1HC100B-Q1
FAULTOpen drain fault test point for the TPS1HC100B-Q1. Pull-up source can be configured using J13.

Table 4-2 Jumper Configurations
JumperFunction/Setting
Current Limit SettingPOT will enabled the physical "Current Limit" potentiometer, DIGI POT will enable the digital potentiometer U3 (TPL0102-100), not populating the jumper will default to the solder down resistor pad R4.
SNS Pot EnableEnables the physical "SNS" potentiometer connected to the current sense output of the TPS1HC100B-Q1. Not populating this jumper will default to the solder down resistor R12.
LDO_EN / LDO_DISEnables and disables the onboard 3.3-V LDO
J13 (Fault Pull-Up)Configures where the fault pin is pulled up from. This jumper will either be from the 3.3-V LDO or the 3.3-V rail from the attached LaunchPad.
LDO to BP PowerConnects the output of the onboard 3.3-V LDO to the 3.3-V rail of the attached BoosterPack. This jumper is used to power the attached LaunchPad using the LDO of the TPS1HC100EVM
DIAG_ENConnects the TPS1HC100B-Q1's DIAG_EN signal to either the LDO's 3.3-V signal or ground
ENConnects the TPS1HC100B-Q1's EN signal to either the LDO's 3.3-V signal or ground
LATCHConnects the TPS1HC100B-Q1's LATCH signal to either the LDO's 3.3-V signal or ground
GND Net BypassBypasses the resistor and diode ground network and connects IC ground to system ground
