6 Specifications

6.1 Absolute Maximum Ratings

over operating junction temperature range (unless otherwise noted).⁽¹⁾⁽²⁾

		MIN	MAX	UNIT
Voltage	Input, V_DD	–0.3	7	V
Voltage	V_MR, V_SENSE1, V_SENSE2, V_SENSE3, V_SENSE4, V_RESET	–0.3	7	V
Current	RESET pin		5	mA
Power dissipation	Continuous total	See Thermal Information
Temperature	Operating virtual junction, T_J	–40	150	°C
	Operating ambient, T_A	–40	125
	Storage, T_stg	–65	150

(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) As a result of the low dissipated power in this device, it is assumed that T_J = T_A.

6.2 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⁾	±500	V

(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.

6.3 Recommended Operating Conditions
