1. GPIO is 1.8V Level
2. The ON_OFF pin commands the EB-5631RE ON or OFF. The turn ON command is a
hardware feature of the Power Control FSM when sensing a rising edge on the pin. The turn
OFF command is a software feature based on interrupts related to rising and/or falling edges
and/or sensing of pin levels.
3. The WAKE_UP pin is an output from the EB-5631RE used to enable an external PMIC. A low
on this output indicates that the EB-5631RE is in one of its low-power states (KA-only,
Hibernate, or Standby mode) and requires no more
than 60μA of current on the VIO_18 input.
A high on this output indicates that the EB-5631RE is in operational mode requiring an
external regulator to provide enough current on both the VIO_18 and VREG_18 inputs to
handle the peak current requirements of the EB-5631RE .
