7.1 Absolute Maximum Ratings⁽¹⁾⁽²⁾⁽³⁾

	MIN	MAX	UNIT
VIN,	-0.3	6.0	V
VIN_IO, VIN_B1, VIN_B2, VIN_B3, SPI_CS, SPI_DI, SPI_CLK, SPI_DO, ENABLE, RESET, PWR_OK, DEVSLP	-0.3	VIN	V
Junction Temperature (T_J-MAX)		150	°C

(1) Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which operation of the device is ensured. Operating Ratings do not imply ensured performance limits. For ensured performance limits and associated test conditions, see the Electrical Characteristics tables.

(2) Internal thermal shutdown protects device from permanent damage. Thermal shutdown engages at T_J = +140°C and disengages at T_J = +120°C (typ.). Thermal shutdown is ensured by design.

(3) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and specifications.

7.2 Handling Ratings

			MIN	MAX	UNIT
T_stg	Storage temperature range		-65	150	°C
V_(ESD)	Electrostatic discharge	Human body model (HBM), per ANSI/ESDA/JEDEC JS-001, all pins⁽¹⁾		1.0	kV

(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.

7.3 Recommended Operating Conditions⁽¹⁾⁽²⁾

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

	MIN	MAX	UNIT
VIN_B1, VIN_B2_VIN_B3, VIN	3.0	5.5	V
VIN_IO	1.75	3.63, but less than VIN	V
Junction Temperature (T_J)	-30	125	°C
Ambient Temperature (T_A)	-30	85	°C
Maximum Continuous Power Dissipation (P_D-MAX) ⁽¹⁾		0.9	W

(1) In applications where high power dissipation and/or poor 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-OP = +125°C), 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-OP – (θ_JA × P_D-MAX).

(2) The amount of Absolute Maximum power dissipation allowed for the device depends on the ambient temperature and can be calculated using the formula: P = (T_J–T_A)/θ_JA, where T_J is the junction temperature, T_A is the ambient temperature, and θ_JA is the junction-to-ambient thermal resistance. θ_JA is highly application and board-layout dependent. Internal thermal shutdown circuitry protects the device from permanent damage (see General Electrical Characteristics)
