1 Introduction

The TPS38700Q1EVM is an evaluation module (EVM) for the TPS38700-Q1 Multichannel I2C Programmable

Voltage Sequencer. Test points are provided to give the user additional access, if needed, for oscilloscope or

multi-meter measurements.

The TPS38700Q1EVM comes pre-populated with TPS38700C03ARGERQ1. This option offers NEM_PD pin

which allow the system to issue an emergency power down while also being able to sequence up to ten different

devices all with a precise predefined sequence. The device also offers the option of battery backup power, a

precise 32.768 kHz clock, and the ability to communicate faults via I2C. ACT and SLEEP pins allow for the

device to change state depending on the logic level present on each. The NIRQ pin serves as an interrupt flag to

alert the system to possible faults, and the NRST pin asserts logic high under reset condition.
