8 Specifications

8.1 Absolute Maximum Ratings

Over operating free-air temperature range (unless otherwise noted) ⁽¹⁾

		MIN	MAX	UNIT
V_IN	Input voltage range	–0.3	6	V
V_BIAS	Bias voltage range	–0.3	6	V
V_OUT	Output voltage range	–0.3	6	V
V_EN, V_SNS, V_PG	EN, SNS, and PG voltage range	–0.3	6	V
I_MAX	Maximum Continuous Switch Current, T_A = 70°C		5	A
I_PLS	Maximum Pulsed Switch Current, pulse <300µs, 2% duty cycle		7	A
T_J,MAX	Maximum junction temperature	Internally limited ⁽²⁾
T_stg	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, 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.

(2) See TSD specification in Electrical Characteristics section and Thermal Considerations section.

8.2 ESD Ratings

			VALUE	UNIT
V_(ESD)	Electrostatic discharge	Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001⁽¹⁾	±2000	V
V_(ESD)	Electrostatic discharge	Charged-device model (CDM), per JEDEC specification JESD22-C101⁽²⁾	±750	V

(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.

8.3 Recommended Operating Conditions

Over operating free-air temperature range (unless otherwise noted)

		MIN	MAX	UNIT
V_IN	Input voltage range	0.7	V_BIAS	V
V_BIAS	Bias voltage range	2.5	5.7	V
V_OUT	Output voltage range	0	5.7	V
V_EN, V_SNS, V_PG	EN, SNS, and PG voltage range	0	5.7	V
T_A⁽¹⁾	Operating free-air temperature range	–40	105	°C
T_J	Operating Junction Temperature	–40	125	°C

(1) 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 [T_A(max)] is dependent on the maximum operating junction temperature [T_J(max)], the maximum power dissipation of the device in the application [P_D(max)], and the junction-to-ambient thermal resistance of the part/package in the application (θ_JA), as given by the following equation: T_A(max) = T_J(max) – (θ_JA × P_D(max))
