Table 3-1 lists the jumper configurations and test points on the EVM.

Table 3-1 TCAN1162EVM Jumper and Test Point Description
DesignatorDescriptionFunction
J62x1 TH headerJ6 connects D1 to the TS pin. This enables the indicator LED to illuminate when the TS pin is low.
J82x1 TH headerJ8 allows the connection of LDO3 (TCAN11623-Q1) or LDO5 (TCAN11625-Q1) to VIO, supplying the IO voltage directly from the integrated LDO on these devices.
J92x1 TH headerJ9 connects nSLP to VIO through a pull-up resistance. Shorting this jumper with a shunt keeps nSLP high indefinitely, leaving the device out of sleep mode.
J122x1 TH headerJ12 connects one 120-Ω resistance to the CAN bus.
J142x1 TH headerJ14 connects INH to GND through a pull-down resistor.
J152x1 TH headerJ15 connects one 120-Ω resistor to the CAN bus.
J162x1 TH headerJ16 shorts VBAT and VSUP together, bypassing the reverse-protection diode.
TP1Red multipurpose test pointTP1 allows the user to probe the VIO pin of the TCAN1162-Q1 device.
TP2Red multipurpose test pointTP2 allows the user to probe the VSUP pin of the TCAN1162-Q1 device.
TP3, TP4Black multipurpose test pointTP3 and TP4 are connected to GND.
TP5Green multipurpose test pointTP5 allows the user to probe the TS pin of the TCAN1162-Q1 device.
TP6Green multipurpose test pointTP6 allows the user to probe the nSLP pin of the TCAN1162-Q1 device.
TP7Green multipurpose test pointTP7 allows the user to probe the RXD pin of the TCAN1162-Q1 device.
TP8Green multipurpose test pointTP8 allows the user to probe the TXD pin of the TCAN1162-Q1 device.
TP9Yellow multipurpose test pointTP9 allows the user to probe the WAKE pin of the TCAN1162-Q1 device.
TP10Yellow multipurpose test pointTP10 allows the user to probe the INH pin of the TCAN1162-Q1 device.
TP11Green multipurpose test pointTP11 allows the user to probe the nRST pin of the TCAN1162-Q1 device.
TP12Red multipurpose test pointTP12 allows the user to probe the LDO5 pin if the TCAN11625-Q1 device is populated on the PCB.
TP13Red multipurpose test pointTP13 allows the user to probe the LDO3 pin oi the TCAN11623-Q1 device is populated on the PCB.
