10 Power Supply Recommendations

The power sequence between the supply rails can be applied in any order as long as SDZ pin is held low. Generally VBAT would be applied before IOVDD and AVDD in most system applications. Once all supplies are stable the SDZ pin can be set high to initialize the part. After a hardware or software reset additional commands to the device should be delayed for 1 mS to allow the OTP to load.
