4 EVM Setup and Operation

This section describes the functionality and operation of the TPS38700Q1EVM. Refer to the TPS38700-Q1 Multichannel I2C Programmable Voltage Sequencer data sheet for details on the electrical characteristics of the device.

The TPS38700Q1EVM comes pre-populated with the TPS38700C03NRGERQ1. The EVM is capable of many different configurations in order to fully evaluate the functionality of all the TPS38700-Q1 device variants. The default configuration of the EVM Jumpers is mentioned in the Table 3-2. The TPS38700Q1EVM comes populated with I2C bus repeater, comparators, LDO, 32.768 kHz crystal and TPS38700C03NRGERQ1 programmable voltage sequencer.

The TPS38700Q1EVM also provides an option to apply a separate pull-up voltage to any of the ENABLE pins by changing the position of jumper J6 to VENx and connecting the pull-up voltage to test points TP23.

Equipment Needed

  • TPS38700Q1EVM
  • TI's USB Interface Adapter (with ribbon cable)
  • Power Supply (3.3 V)
  • Function Generator (provide pulse input for evaluation)
  • Multi-channel Oscilloscope (review evaluation waveforms)
  • Jumper Cables (additional evaluation)
