SNAS633A March 2014 – September 2014 LMP93601
PRODUCTION DATA.
The LMP93601 requires two sources of power, AVDD and IOVDD. These pins can be supplied from the same supply rail as the MCU, from separate regulators or from a battery source. However, it is recommend that the MCU and the IOVDD share the same supply and the AVDD be supplied from a separate regulator. In any case, for proper operation, the supply range must remain within the 2.7 V to 5.5 V limits and IOVDD must always be lower than or equal to AVDD supply. It is highly recommended that during power up, the AVDD and IOVDD supplies ramp up in a manner to ensure the "IOVDD ≤ AVDD" requirement is not violated.
