2.3.1 EVM Test Points

Table 3-1 lists the EVM test points as well as their functional descriptions. All TPS389C03-Q1 pins have a corresponding test point on the EVM, these test points are located close to the pins for more accurate measurements. Additionally, multiple test-points offer dual functionality allowing for every possible variant of the TPS389C0X-Q1 device to be evaluated. In addition to the test points listed below, the EVM also has four additional GND test points.

Table 2-1 Test Points
TEST POINT SILKSCREEN LABEL FUNCTION DESCRIPTION (1)
MON1/WDE Connection to MON1 pin or Watchdog Enable pin Allows the user to monitor voltage rail #1 or control state of the watchdog enable pin.
MON2 Connection to MON2 pin Allows the user to monitor voltage rail #2.
MON3 Connection to MON3 pin Allows the user to monitor voltage rail #3.
MON4 Connection to MON4 pin Allows the user to monitor voltage rail #4.
MON5/RS_4 Connection to MON5 pin or to RS_4 pin Allows the user to monitor voltage rail #5 or allows the user to remote sense MON4.
MON6/RS_3 Connection to MON6 pin or to RS_3 pin Allows the user to monitor voltage rail #6 or allows the user to remote sense MON3.
RS_1/2 Connection to RS_1/2 pin Allows the user to remote sense MON1 or MON2.
NRST Connection to NRST pin Allows the user to monitor the reset (NRST) output.
ADDR Connection to ADDR pin Allows the user to measure the I2C address voltage.
NIRQ Connection to NIRQ pin Allows the user to monitor the interrupt (NIRQ) output.
ACT/WDO Connection to ACT pin or WDO pin Allows the user to set the ACT input to VDD or GND. Alternatively allows the user to monitor the watchdog output (WDO) pin.
ESM/WDI Connection to ESM or WDI pin Allows the user to set the error signal monitor input or interact with the watchdog input pin.
SCL Connection to SCL pin Allows the user to monitor the clock signal input.
SDA Connection to SDA pin Allows the user to monitor the data signal input.
PEXT External power supply Allows the user to apply a power supply voltage that is not provided from the EVM.
GND GND for EVM GND for EVM.
(1) Test point functionality is dependent on TPS389C0x-Q1 variant used.
