Bootstrap

The AUIPS7221 integrates a bootstrap regulator to maintain a fixed voltage on the bootstrap capacitor for any battery

voltage. The regulator is off during the sleep mode to reduce the current consumption.

Load

The 8mA current source flows permanently on the output when the output is off and the part is not in sleep mode. In case

of an open load condition, the output voltage will be at Vcc-6V.

Wake up sequence

To wake up the part from the sleep mode, the input must be activated at least during Twkp, then the boostrap regulator is

switched on and the boostrap capacitor is charged. The output will be not activated during Tpw on rst.

products are specifically designated by IR as military-grade or “enhanced plastic.” Only products designated by IR as

military-grade meet military specifications. Buyers acknow ledge and agree that any such use of IR products which IR has

not designated as military-grade is solely at the Buyer’s risk, and that they are solely responsible for compliance with all

legal and regulatory requirements in connection with such use.

IR products are neither designed nor intended for use in automotive applications or environments unless the specific IR

products are designated by IR as compliant with ISO/TS 16949 requirements and bear a part number including the

designation “AU”. Buyers acknowledge and agree that, if they use any non-designated products in automotive

applications, IR will not be responsible for any failure to meet such requirements.
