Hi Rahul,
haven't explored the datasheet too much, but it looks like a 3.3V device, while Arduino Micro is running at 5V, right? If so, your design would benefit from a level shifter, like this one: SparkFun Voltage-Level Translator Breakout - TXB0104 - BOB-11771 - SparkFun Electronics
Now, check if you can also use its enable (OE) pin and one of its channels for powering your chip(s) up and down.
Cheers,
Dmitriy.
