6 Specifications

6.1 Absolute Maximum Ratings

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

		MIN	MAX	UNIT
Supply voltage, V_CC	(Internally clamped)		20	V
Input current into V_CC clamp	I_DD		30	mA
Input current	ZCD		±10	mA
Gate drive current (peak), I_DRV	DRV		±750	mA
Input voltage, V_CC	VO_SNS, MULTIN, CS		5	V
Maximum negative voltage	VO_SNS, MULTIN, DRV, CS		–0.5	V
Power dissipation at T_A = 50°C	D package		650	mW
Power dissipation at T_A = 50°C	P package		1	W
Operating junction temperature range, T_J		–55	150	°C
Storage temperature, T_stg		–65	150	°C
Lead temperature 1,6 mm (1/16 inch) from case for 10 seconds			300	°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.

6.2 ESD Ratings

			VALUE	UNIT
SOIC PACKAGE
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

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

		MIN	NOM	MAX	UNIT
VCC input voltage from a low-impedance source		VCC_OFF + 1 V		18	V
Operating junction temperature, T_J		–40		125	°C
