Setup
4.3.1 J4 - SLP_SUS#
SLP_SUS# is active low and when set low will put the device into sleep state SUSPEND. When
SLP_SUS# asserts high, VR5 and VR1 turn on as well as the device enabling a load switch.
4.3.2 J4 - SLP_S4#
SLP_S4# is active low and when set low will put the device into sleep state 4. When SLP_4# asserts high,
VR4 turns on as well as the device enabling a load switch.
4.3.3 J4 - SLP_S3#
SLP_S3# is active low and when set low will put the device into sleep state 3. When SLP_3# asserts high,
the device enables a load switch.
4.3.4 J4 - SLP_S0#
SLP_S0# is active low and when set low will put the device into sleep state 0. When SLP_0# asserts high,
VLDO1 turns on.

5.1 Hardware Setup
Figure 8. Hardware Board Connection
Before connecting the EVM, always remember to preset the power supply to correct voltages. Never "hot
plug" or connect the power supply to the EVM with the power supply on. This can result in 2x input voltage
overshoot that can damage the devices on the EVM.
Connect the EVM as shown in Figure 8 . Before turning on the power supply, set the SLP_Sx# jumpers to
LOW as they must be sequenced in the proper order for correct power up. The order for sequence is
SLP_SUS#
→ SLP_S4# → SLP_S3# → SLP_S0#.
Once the power supply is on and providing a valid VIN voltage, the SLP_Sx# signal can be set to HIGH in
the listed sequence. After this, the EVM will have all power rails ON and regulating to their set voltage.
ALL_SYS_PWRGD, TP71, should be HIGH signaling a valid power up of the system.
5.2 Software Setup
