(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) All voltages are with respect to GND. Currents are positive into and negative out of the specified terminal.

(3) Whichever is larger

6.2 ESD Ratings

			VALUE	UNIT
V_(ESD)	Electrostatic discharge	Human body model (HBM), per ANSI/ESDA/JEDEC JS-001, all pins⁽¹⁾	±4000	V
V_(ESD)	Electrostatic discharge	Charged device model (CDM), per JEDEC specification JESD22-C101, all pins⁽²⁾	±1000	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	MAX	UNIT
T_J	Operating junction temperature	–55	125	°C

6.4 Thermal Information

THERMAL METRIC⁽¹⁾		UCC27423-EP	UCC27424-EP	UNIT
		D	DGN
		8 PINS
R_θJA	Junction-to-ambient thermal resistance	111.4		°C/W
R_θJC(top)	Junction-to-case (top) thermal resistance	70.8

6.5 Power Dissipation Ratings

PACKAGE	SUFFIX	R_θJC (°C/W)	R_θJA (°C/W)	POWER RATING (mW) T_A = 70°C	DERATING FACTOR ABOVE 70°C (mW/°C)
MSOP-8 PowerPAD⁽³⁾	DGN	4.7	50 to 59	1370⁽¹⁾	17.1⁽¹⁾
SOIC 8	D	42	84 to 160	344 to 655⁽²⁾⁽⁴⁾	6.25 to 11.9⁽²⁾⁽⁴⁾

(1) 150°C operating junction temperature is used for power-rating calculations.

(2) The range of values indicates the effect of PCB. These values are intended to give the system designer an indication of the best- and worst-case conditions. In general, the system designer should attempt to use larger traces on the PCB where possible, in order to spread the heat away from the device more effectively. For information on the PowerPAD package, refer to technical brief, PowerPad™ Thermally-Enhanced Package, SLMA002, and application brief, PowerPad™ Made Easy, SLMA004.

(3) The PowerPAD package is not directly connected to any leads of the package. However, it is electrically and thermally connected to the substrate, which is the ground of the device.

(4) 125°C operating junction temperature is used for power-rating calculation.

(1) Specified by design. Not tested in production.

(2) The pullup/pulldown circuits of the driver are bipolar and MOSFET transistors in parallel. The pulsed output current rating is the combined current from the bipolar and MOSFET transistors.

(3) The pullup/pulldown circuits of the driver are bipolar and MOSFET transistors in parallel. The output resistance is the R_DS(ON) of the MOSFET transistor when the voltage on the driver output is less than the saturation voltage of the bipolar transistor.
