3.1 Software Description

This section describes the software functionality and operation of this EVM. Refer to the TPS389006 and TPS38700S-Q1 data sheet for details on the electrical characteristics of the respective devices.

The EVM comes pre-populated with a TPS389006 I2C programmable 6 channel supervisor and a TPS38700S-Q1 I2C programmable 6 channel sequencer, and a 12 rail programmable virtual power tree generated from the MSP430 launchpad dev board. This EVM is capable of different configurations to fully evaluate the functionality and interactions between the TPS389006 and TPS38700S-Q1 device variants. With the current devices, the EVM can monitor and sequence up to 6 channels.

The default configuration of the EVM Jumpers is referenced in Table 3-2.Consult the Device Threshold Table in the TPS389006-Q1 data sheet to verify proper voltage monitored values.

To test the functionality of TPS389387EVM, go to TPS389387EVM Evaluation Instructions.

To communicate with the TPS38700S-Q1 and TPS389387EVM, including reading and writing to the registers, as well as clearing interrupts, follow TPS38700-Q1 GUI instructions.
