IN out diag internal diag Tdiag Treset Tdiag Tsleep Normal mode Fault mode sleep mode Figure 1 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. Vcc 8mA Cboot 6V Out 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. www.irf.com 6 AUIPS7221R Tsleep IN Tpw on rst out Twkp sleep mode Normal mode sleep mode Figure 2 IN out Tpw on rst Twkp sleep mode Normal mode Figure 3 www.irf.com 7 AUIPS7221R 200% 40 Rds(on), Drain-to-Source On Resistance (Normalized) Isd, Over-current shutdown (A) -50 0 50 100 150 30 150% 20 100% 1 0 50% 0 -50 0 50 1 00 1 50 Tj, junction temperature (C) Figure 5 - Normalized Rds(on) (%) Vs Tj (C) Tj, junction temperature (C) Figure 6 - Isd (A) Vs Tj (C) 0.5 2.0 0.4 tr tf On and Off delay time (s) 1.5 Rising and falling time (s) 0.3 1.0 0.2 tdon 0.5 0.1 tdoff 0.0 -50 0.0 -50 0 50 100 150 0 50 100 150 Tj, junction temperature (C) Tj, junction temperature (C) Figure 8 - tdon / tdoff (s) Vs Tj (C) Figure 7 - tr / tf (s) Vs Tj (C) www.irf.com 8 AUIPS7221R Zth, transient thermal impedance (C/W) 1 00 5 Icc off, supply leakage current (A) 1 e-4 1 e-3 1 e-2 1 e-1 1 e+0 1 e+1 1 e+2 1 e+3 4 1 0 3 1 2 0.1 1 0.01 1 e-5 0 -50 0 50 100 150 Time (s) Figure 9 - Transient thermal impedance (C/W) Vs time (s) Tj, junction temperature (C) Figure 10 - Icc off (A) Vs Tj (C) 0.20 Icc off, supply current (A) 0.15 0.10 0.05 0.00 0 10 20 30 40 50 Vcc, supply voltage (V) Figure 11 - Icc off(A) Vs Vcc (V) www.irf.com 9 AUIPS7221R Case Outline 5 Lead - DPAK www.irf.com 10 AUIPS7221R Tape & Reel 5 Lead - DPAK www.irf.com 11 AUIPS7221R Part Marking Information Ordering Information Base Part Number Standard Pack Package Type Form Quantity Complete Part Number Tube AUIPS7221R D-Pak-5-Lead Tape and reel Tape and reel left Tape and reel right 75 2000 3000 3000 AUIPS7221R AUIPS7221RTR AUIPS7221RTRL AUIPS7221RTRR www.irf.com 12 AUIPS7221R IMPORTANT NOTICE Unless specifically designated for the automotive market, International Rectifier Corporation and its subsidiaries (IR) reserve the right to make corrections, modifications, enhancements, improvements, and other changes to its products and services at any time and to discontinue any product or services without notice.

IR products are neither designed nor intended for use in military/aerospace applications or environments unless the IR products are specifically designated by IR as military-grade or "enhanced plastic." Only products designated by IR as military-grade meet military specifications. Buyers acknowledge 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.
