2.3 Header Information

J6 header contains numerous pinout from TPS25751 for testing, evaluation, and debugging purposes. The header pins are clearly labeled on the top layer of the TPS25751EVM for easy access, for details see Table 2-1. Pin 1 is indicated by a white circle, see Figure 2-1 for reference.

Table 2-1 J6 Header Pinout
Pin Number Pin Label Description
1 GND Ground reference for EVM
2 GND Ground reference for EVM
3 I2Cc_SCL I2C controller clock line of TPS25751
4 GPIO0 GPIO0 of TPS25751
5 I2Cc_SDA I2C controller data line of TPS25751
6 GPIO1 GPIO1 of TPS25751
7 I2Cc_IRQ I2C controller interrupt line of TPS25751. This can also be reconfigured to GPIO12.
8 GPIO2 GPIO2 of TPS25751
9 751_CC2 CC2 pin of J3 Type-C port, used for PD negotiation. This can be VCONN or CC depending on the polarity flip of the USB Type-C cable.
10 GPIO3 GPIO3 of TPS25751
11 751_CC1 CC1 pin of J3 Type-C port, used for PD negotiation. This can be VCONN or CC depending on the polarity flip of the USB Type-C cable.
12 GPIO4 GPIO4 of TPS25751
13 GND Ground reference for EVM
14 GPIO5 GPIO5 of TPS25751
15 I2Ct_SCL I2C target clock line of TPS25751
16 GPIO6 GPIO6 of TPS25751
17 I2Ct_SDA I2C target data line of TPS25751
18 GPIO7 GPIO11 of TPS25751
19 I2Ct_IRQ I2C target interrupt line of TPS25751. This can also be reconfigured to GPIO10.
20 GPIO11 GPIO11 of TPS25751
21 GND Ground reference for EVM
22 NC No connection, do not use
23 VBUS_DIV2 Resistor divider output of VBUS line between TPS25751 and J3 Type-C port. This output pin halves the voltage of VBUS for digital scopes. For example, when VBUS is at 20V, pin 23 is measured at 10V.
24 PPHV_DIV2 Resistor divider output of PPHV pin from TPS25751. This output pin halves the voltage of PPHV for digital scopes. For example when PPHV is at 20V, pin 24 is measured at 10V.
25 GND Ground reference for EVM
26 NC No connection, do not use
27 VIN3V3 3.3V supply connected to VIN_3V3 of TPS25751
28 PP5V 5V supply connected to PP5V of TPS25751
29 GND Ground reference for EVM
30 GND Ground reference for EVM
Note: Rev A2 added PPHV_DIV2 capability, this is not included on Rev A1 EVM hardware.
