TPS389387EVM Joint Evaluation Module

Description

The TPS389387EVM demonstrates the functionality

of the TPS38700S-Q1 sequencer and TPS389006

voltage monitoring device. If needed, then connectors

and pins are provided to give the user access for

oscilloscope or multi-meter measurements.

The EVM comes pre-populated with two devices: a

TPS389006 I2C programmable 6 channel supervisor

and a TPS38700S-Q1 I2C programmable 6 channel

sequencer. The EVM is intended to be operated with

an up to 12 rail programmable virtual power tree

generated from MSP430 launchpad dev board. This

EVM must be used with the MSP430 MCU variant,

MSP430FR2355.

Get Started

1. Order the TPS3839387EVM.

2. Order additional components

a. MSP430 MCU variant, MSP430FR2355

(MSP-EXP430FR2355).

b. USB-TO-GPIO2 connector (USB-TO-GPIO2).
