... Enable pin. A 10kohm resistor and a 0.1uF are all that is required. If the system needs to externally control the Enable pin as well recommended that the Enable pin be pulled to ground using an open drain I/O. Using 3.3V active logic would back feed DVDD and exceed the maximum rated voltage of the pin. © 2011 Exar Corporation ...
Page 13
... When the Enable is asserted, the chip will power up and VCCA will regulate at 5.1V. If our device is sequenced properly, VCCA will achieve 5.1V then drop down to 4.6V and toggle back to 5.1V. See Figure 22 for an example. © 2011 Exar Corporation Q u ...

... The dead time between the turn off of the low side MOSFET and the turn on of high side MOSFET is controlled by the SET_DT_RISE_CHx. On the other hand, the dead time between the turn off of high side MOSFET and the turn on of the low side MOSFET is controlled by SET_DT_FALL_CHx. The actual LSB of the registers is variable depending on the switching frequency. © 2011 Exar Corporation ...

... The warning threshold is configurable Degrees C below the fault threshold. When the junction temperature reaches Degrees C below the user defined set point, the over- temperature warning bit [OTPW] gets set in the READ_OVV_UVLO_OVT_FLAG register to warn the user that the IC might go into an over temperature condition (and shutdown all of the regulators). © 2011 Exar Corporation ...

... The 7-bit address plus the R/W bit create an 8-bit data value that is sent on the bus. The XRP7714ILB-0X10-F has data value of 0x20 and read by sending a data value of 0x21. This reflects the address being shifted one bit to the left and the least significant bit being set to reflect a read or write operation in order to stuff the byte correctly ...
