Table 2-10 Test Points
DesignatorNameDescription
TP1GPIO0_FAULTzFault terminal,which is pulled LOW when an internal fault occurs.
TP2GPIO1_Hybrid_ProGeneral-purpose input/output configured to be the Class-H PWM control pin.
TP3GPIO2_PD_DETPVDD Drop detection, which is pulled LOW when the PVDD drop below 8 V.
TP4PDNPower down, active-low. PDN place the amplifier in Shutdown, turn off all internal regulators.
TP5VINBattery input voltage into the LM5155.
TP6VOUTLM5155 boost output voltage
TP7FBLM5155 Feedback pin used to control the output boost voltage
TP13SCL_XMOSProbe point for the I2C serial clock input going generated by the XMOS.
TP14SDA_XMOSThe I2C serial control data interface input/output generated by the XMOS.
TP16SCLKBit clock for the digital signal that is active on the input data line of the serial data port.
TP17LRCLKWord select clock for the digital signal that is active on the serial port's input data line. In I2S, LJ and RJ, this corresponds to the left channel and right channel boundary. In TDM mode, this corresponds to the frame sync boundary.
TP18SDINData line to the serial data port.
TP19SCL_AMPProbe point for the I2C serial clock input going into the TAS5827.
TP20SDA_AMPThe I2C serial control data interface input/output going into the TAS5827.
TP21BST_A+The voltage at the OUT_A+ bootstrap capacitor which is used to create a power supply for the high-side gate drive for OUT_A+.
TP22BST_A-The voltage at the OUT_A- bootstrap capacitor which is used to create a power supply for the high-side gate drive for OUT_A-.
TP23BST_B+The voltage at the OUT_B+ bootstrap capacitor which is used to create a power supply for the high-side gate drive for OUT_B+.
TP24BST_B-The voltage at the OUT_B- bootstrap capacitor which is used to create a power supply for the high-side gate drive for OUT_B-.
TP251 VThe 1 V rail used in the XMOS.
All other TPGNDGround reference pins for probes.
