The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. Absolute Maximum Ratings (1) (2) (3) Supply Voltage(1) 6.0V Storage Temperature −65°C to +150°C Voltage at Any Input Pin VDD + 0.3V ≥ V ≥ GND - 0.3V Power Dissipation(4) Internally Limited ESD Susceptibility, all other pins(5) 2.0kV ESD Susceptibility(6) 200V Junction Temperature (TJMAX) 150°C Thermal Resistance θJA (DSBGA) 220°C/W θJA (WSON) 73°C/W Soldering Information See (SNVA009) "microSMD Wafers Level Chip Scale Package." (1) All voltages are measured with respect to the ground pin, unless otherwise specified. (2) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is functional, but do not ensure specific performance limits. Electrical Characteristics state DC and AC electrical specifications under particular test conditions which ensure specific performance limits. This assumes that the device is within the Operating Ratings. Specifications are not ensured for parameters where no limit is given, however, the typical value is a good indication of device performance. (3) If Military/Aerospace specified devices are required, please contact the TI Sales Office/ Distributors for availability and specifications. (4) The maximum power dissipation must be derated at elevated temperatures and is dictated by TJMAX, θJA, and the ambient temperature TA. The maximum allowable power dissipation is PDMAX = (TJMAX–TA)/θJA or the number given in Absolute Maximum Ratings, whichever is lower. For the LM4675, TJMAX = 150°C. The typical θJA is 99.1°C/W for the DSBGA package. (5) Human body model, 100pF discharged through a 1.5k Ω resistor. (6) Machine Model, 220pF – 240pF discharged through all pins. Operating Ratings (1) (2) Temperature Range TMIN ≤ TA ≤ TMAX −40°C ≤ TA ≤ 85°C Supply Voltage 2.4V ≤ VDD ≤ 5.5V (1) All voltages are measured with respect to the ground pin, unless otherwise specified. (2) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is functional, but do not ensure specific performance limits. Electrical Characteristics state DC and AC electrical specifications under particular test conditions which ensure specific performance limits. This assumes that the device is within the Operating Ratings.
