2.4 Jumper Information

J3 TVSP Jumper

This jumper selects the boot mode and I2C address for TPS25763-Q1.

TPS25763Q1EVM J3 TVSP Jumper Figure 2-2 J3 TVSP Jumper

See the RTVSP Configuration Settings table in the TPS25763-Q1 Automotive Single USB Type-C Alternate Mode Power Delivery Controller with Buck-Boost Regulator data sheet for selection description.

J8 I2C Connection Jumper

This jumper block expands the I2C1 connections of TPS2573DQ1. The jumper can connect to the I2C temperature sensor and EEPROM. Since I2C bus can support multiple targets, TI recommends to connect all pins.

4-5 and 7-8 EEPROM Connect the I2C1 bus of TPS25763-Q1 to the on board EEPROM

J4 NTC Selection Jumper

The J4 header is used to verify the Thermal Foldback function. The NTC pin detects the voltage of an external NTC circuit. The pin can be connected to a thermistor (NTC or PTC) divider or users can directly apply an external voltage to NTC contact pin without any jumper. The thermistor assembled on the EVM is positive temperature coefficient (PTC).

J7 TMP75B-Q1 Alert Connection Jumper

The J7 jumper can be used to test the function of an I2C controlled temperature sensor in place of the NTC/PTC/resistor divider circuit. The temperature feedback is available via I2C or the ALERT signal can directly be connected to the TPS2673-Q1 NTC pin.

5:6Connect the active low output of the Alert pin of TMP75B-Q1 to the NTC pin of TPS25763-Q1

J23, J5, J6, J19, J16, J17 Power Selection Jumpers

Controls whether a given peripheral circuit is powered by VCC3V3 (external LDO) or LDO_3V3 (internal LDO of TPS25763-Q1). This allows users to evaluate whether the system requires an external 3.3V supply. Additionally, a better efficiency measurement of TPS25763-Q1 can be made by removing all Power Selection jumpers.

J21, J20, J22, J1, J2 DisplayPort MUX Configuration Jumpers

Dictates whether TUSB1064 is controlled by TPS25763-Q1 via GPIO signals or I2C commands. The MUX I2C feature is enabled or disabled, then the appropriate signal routing can be made between the MUX and PD controller. If the MUX I2C feature is disabled, then expect the remaining jumpers to be set for GPIO control. Similarly, if the MUX I2C feature is enabled, then expect the remaining jumpers to be set for I2C control.

J18 !USB2.0 Data Jumper

Install if USB2.0 data is not required for the system (charge only). This does not impact DisplayPort over USB-C functionality. Installing this jumper causes D+/D- from the Type-C connector to route to TPS25763-Q1 via TS3USB221A-Q1, enabling legacy charging algorithms such as BC1.2.

TPS25763Q1EVM !USB2.0 Data Jumper Figure 2-8 !USB2.0 Data Jumper
Pins Description
1:2 USB2.0 data is not passed through to an upstream port. D+/D- from the Type-C receptacle are routed to TPS25763-Q1 for legacy charge handshake capability.
Open USB2.0 data is passed through to upstream port J29. Legacy charge compatibility is unavailable unless implemented in the upstream port.
