SiP32448, SiP32449 www.vishay.com Vishay Siliconix 1.7 V to 5.5 V, 3 A Load Switch with Negative V Tolerance IN DESCRIPTION FEATURES The SiP32448 and SiP32449 are low resistance slew rate 1.7 V to 5.5 V input voltage range controlled load switches. The part operates from 1.7 V to Negative input voltage tolerance down to -2 V 5.5 V supply and can tolerate negative voltage at input to 38 m typical R from 1.8 V to 5 V ON -2 V. The integrated charge pump drivers enable the part 3 A maximum continuous switch current with low on resistance over the wide input voltage range. Slew rate controlled turn-on: 2.5 ms at 3.6 V Available Both SiP32448 and SiP32449 feature a controlled soft-on slew rate of typical 2.5 ms that limits the inrush current for Constant low control logic: V = 1.15 V, V = 0.7 V IH IL designs of heavy capacitive load and minimizes the resulting 2 V UVLO when EN is open voltage droop at the power rails. Reverse current blocking when switch is off or V is ground IN The SiP32448 and SiP32449 feature a constant low voltage Output discharge (SiP32449) control logic interface over the full operation voltage range. ESD protected It can interface with low voltage control signals without extra - HBM: >6 kV level shifting circuit. When EN is left open, the part will not - MM: >300 V turn on until V is greater than 2.5 V. IN - IEC61000-4-2 air discharge: >15 kV The SiP32449 has a output discharge to help discharge the - IEC61000-4-2 contact discharge: >8 kV output capacitor during shutdown mode for fast turn off. Compact TDFN4 package The SiP32448 and SiP32449 have exceptionally low Material categorization: for definitions of compliance shutdown current and provides reverse blocking to prevent please see www.vishay.com/doc 99912 high current flowing into the power source when the switch is off or V is ground.
