7.1 Absolute Maximum Ratings

Over operating free-air temperature (unless otherwise noted)(1)(2)
MIN MAX UNIT
VIN Input voltage –0.3 6 V
VBIAS Bias voltage –0.3 6 V
VOUT Output voltage –0.3 6 V
VON ON voltage –0.3 6 V
IMAX Maximum continuous switch current, TA = 65°C (DGK Package) 4 A

Maximum pulsed switch current, pulse <300 µs, 2% duty cycle (DGN Package) 8 A
TJ Maximum junction temperature 125 °C
Tstg Storage temperature range –65 150 °C
(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) All voltage values are with respect to network ground terminal.

7.2 ESD Ratings

VALUE UNIT
V(ESD) Electrostatic discharge Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) ±2000 V
Charged-device model (CDM), per JEDEC specification JESD22-C101(2) ±1000
(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. Manufacturing with less than 500-V HBM is possible with the necessary precautions.
(2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process. Manufacturing with less than 250-V CDM is possible with the necessary precautions.

7.3 Recommended Operating Conditions

MIN MAX UNIT
VIN Input voltage range 0.6 VBIAS V
VBIAS Bias voltage range 2.5 5.5 V
VON ON voltage range 0 5.5 V
VOUT Output voltage range VIN V
VIH, ON High-level input voltage, ON VBIAS = 2.5 to 5.5 V 1.2 5.5 V
VIL, ON Low-level input voltage, ON VBIAS = 2.5 to 5.5 V 0 0.5 V
TA Operating free-air temperature (2) –40 105 °C
CIN Input capacitor 1(1) µF
(1) Refer to the Application Information section.
(2) In applications where high power dissipation and/or poor package thermal resistance is present, the maximum ambient temperature may have to be derated. Maximum ambient temperature [TA(max)] is dependent on the maximum operating junction temperature [TJ(max)], the maximum power dissipation of the device in the application [PD(max)], and the junction-to-ambient thermal resistance of the part/package in the application (RθJA), as given by the following equation: TA(max) = TJ(max) – (RθJA × PD(max)).
