7 Specifications

7.1 Absolute Maximum Ratings

Over operating free-air temperature range (unless otherwise noted)(1)
MIN MAX UNIT
VIN Input voltage –0.3 6 V
VOUT Output voltage –0.3 6 V
VBIAS Bias voltage –0.3 6 V
VON On voltage –0.3 6 V
IMAX Maximum continuous switch current 6 A
IPLS Maximum pulsed switch current, pulse < 300 µs, 2% duty cycle 8 A
TJ Maximum junction temperature 125 °C
Tstg Storage temperature –65 150 °C
(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

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.
(2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.

7.3 Recommended Operating Conditions

MIN MAX UNIT
VIN Input voltage 0.6 VBIAS V
VBIAS Bias voltage 2.5 5.7 V
VON ON voltage 0 5.7 V
VOUT Output voltage VIN V
VIH High-level input voltage, ON VBIAS = 2.5 V to 5 V, TA< 85°C 1.05 5.7 V
VBIAS = 2.5 V to 5 V, TA< 105°C 1.1 5.7
VBIAS = 5 V to 5.7 V, TA< 105°C 1.2 5.7
VIL Low-level input voltage, ON VBIAS = 2.5 V to 5.7 V 0 0.5 V
CIN Input capacitor 1(1) µF
TA Operating free-air temperature(1)(2) –40 105 °C
(1) See 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 and device lifetime may be affected. 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 (θJA), and can be approximated by the following equation: TA (max) = TJ(max) – (θJA × PD(max)).
