2.1 EVM Setup

Table 3-1 lists the jumper connections and the jumper description.

Table 2-1 Jumper Descriptions

Jumper Name

Description

J1

Provide the I2C pull-up to 3p3 V. Note: The USB2ANY provides this pull-up when using the TI Charger GUI.

J2

VIN and GND connector. Input voltage from external power supply. Recommended voltage is 5V and OVP is 5.7V. Max input voltage is 25V while in OVP.

J3

VBAT and GND connector. Battery connection using jumper for easy access.

J4

Battery pack connector. Battery connection using JST header.

J5

TS potentiometer connector. Connects TS potentiometer to TS pin. Leaving this jumper leaves the TS pin open.

J6

USB2ANY connector. For connecting the device to the USB2ANY evaluation board to allow computer to interface with the EVM.

J7

VIO connector to 3p3 V. This is supplied by an external on-board LDO. Pulls the /PG and /INT high when populated.

J8, J9

Board connector to the other module.

J10

Power Good (PG) LED jumper

J11

VSYS and GND connector.

J13

/CE connector. Connects /CE pin to high or low setting.

J14

Micro USB connector (optional for VIN)
