Introduction
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 TPS38700C03NRGERQ1. 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.

EVM Connectors
3 EVM Connectors
This section describes the connectors, jumpers, and test points on the EVM as well as how to connect, set up,
and properly use the EVM. Each device has an independent supply connection, but all grounds are connected
on the board.
3.1 EVM Test Points
Table 3-1 lists the EVM test points as well as their functional descriptions. All TPS38700-Q1 pins have a
corresponding test point on the EVM. These test points are located close to the pins for more accurate
measurements. In addition to the test points listed below, the EVM also has four additional GND test points.
