3 / 22 page LMP8640 LMP8640HV www.ti.com SNOSB28F – AUGUST 2010 – REVISED APRIL 2013 Operating Ratings (1) Supply Voltage (VS = V + - V−) 2.7V to 12V Temperature Range (2) -40°C to 125°C Package Thermal Resistance(2) SOT-6 96°C/W (1) “Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur, including inoperability and degradation of device reliability and/or performance. Functional operation of the device and/or non-degradation at the Absolute Maximum Ratings or other conditions beyond those indicated in the Operating Ratings is not implied. Operating Ratings indicate conditions at which the device is functional and the device should not be operated beyond such conditions. (2) The maximum power dissipation must be derated at elevated temperatures and is dictated by TJ(MAX), θJA, and the ambient temperature, TA. The maximum allowable power dissipation PDMAX = (TJ(MAX) - TA)/ θJA or the number given in Absolute Maximum Ratings, whichever is lower. 2.7V Electrical Characteristics (1) Unless otherwise specified, all limits ensured for at TA = 25°C, VS=V + – V-, V SENSE= +IN-(-IN), V + = 2.7V, V− = 0V, −2V < V CM < 76V, RL = 10MΩ. Boldface limits apply at the temperature extremes.

Factory testing conditions result in very limited self-heating of the device such that TJ = TA. No specification of parametric performance is indicated in the electrical tables under conditions of internal self-heating where TJ > TA. Absolute Maximum Ratings indicate junction temperature limits beyond which the device may be permanently degraded, either mechanically or electrically. (2) Limits are 100% production tested at 25°C. Limits over the operating temperature range are ensured through correlations using statistical quality control (SQC) method. (3) Typical values represent the most likely parametric norm at the time of characterization. Actual typical values may vary over time and will also depend on the application and configuration. The typical values are not tested and are not ensured on shipped production material. (4) Offset voltage temperature drift is determined by dividing the change in VOS at the temperature extremes by the total temperature change. (5) This parameter is ensured by design and/or characterization and is not tested in production. (6) Positive Bias Current corresponds to current flowing into the device.
