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) Supply Voltage −0.3V to 6.0V Voltage at SMBDAT, SMBCLK, TCRIT1, TCRIT2, TCRIT3 −0.5V to 6.0V Voltage at Other Pins −0.3V to (VDD + 0.3V) D − Input Current ±1 mA Input Current at All Other Pins(2) ±5 mA Package Input Current(2) 30 mA SMBDAT, TCRIT1, TCRIT2, TCRIT3 Output Sink Current 10 mA Storage Temperature −65°C to +150°C ESD Susceptibility(3) Human Body Model 2000V Machine Model 200V Charge Device Model 1000V Soldering process must comply with TI’s reflow temperature profile specifications. Refer to http://www.ti.com/packaging(4) (1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. DC and AC electrical specifications do not apply when operating the device beyond its rated operating conditions. (2) When the input voltage (VI) at any pin exceeds the power supplies (VI < GND or VI > VDD), the current at that pin should be limited to 5 mA. Parasitic components and or ESD protection circuitry are shown in Table 1 for the LM95234's pins. (3) Human body model, 100 pF discharged through a 1.5 k Ω resistor. Machine model, 200 pF discharged directly into each pin. Charged Device Model (CDM) simulates a pin slowly acquiring charge (such as from a device sliding down the feeder in an automated assembler) then rapidly being discharged. (4) Reflow temperature profiles are different for packages containing lead (Pb) than for those that do not. Operating Ratings Operating Temperature Range −40°C to +140°C Electrical Characteristics Temperature Range TMIN ≤ TA ≤ TMAX LM95234CISD −40°C ≤ TA ≤ +125°C Supply Voltage Range (VDD) +3.0V to +3.6V 4 Submit Documentation Feedback Copyright © 2006–2013, Texas Instruments Incorporated Product Folder Links: LM95234 |
