8 / 49 page Analog Integrated Circuit Device Data 8 Freescale Semiconductor 34937A ELECTRICAL CHARACTERISTICS MAXIMUM RATINGS ESD Voltage(6) Human Body Model - HBM (All pins except for the pins listed below) Pins: PA_Boot, PA_HS_S, PA_HS_G, PB_Boot, PB_HS_S, PB_HS_G, PC_Boot, PC_HS_S, PC_HS_G, VPWR Charge Device Model - CDM Corner pins All other pins VESD ±2000 ±1000 ±750 ±300 V THERMAL RATINGS Storage Temperature TSTG -55 to +150 °C Operating Junction Temperature (7) TJ -40 to +150 °C Thermal Resistance (8) Junction-to-Case RJC 3.0 °C/W Soldering Temperature(9) TSOLDER Note 10 °C Notes 6. ESD testing is performed in accordance with the Human Body Model (HBM) (CZAP = 100 pF, RZAP = 1500 W) and the Charge Device Model (CDM), Robotic (CZAP = 4.0 pF). 7. In order to meet or exceed the expected reliability performance level over 10 years of continuous operation, the user must take measures to guarantee that the device’s average junction temperature does not exceed 125ºC. The device’s maximum junction temperature remains as specified in the data sheet. 8. Case is considered EP - pin 55 under the body of the device. The actual power dissipation of the device is dependent on the operating mode, the heat transfer characteristics of the board and layout and the operating voltage. See Figure 24 and Figure 25 for examples of power dissipation profiles of two common configurations. Operation above the maximum operating junction temperature will result in a reduction in reliability leading to malfunction or permanent damage to the device. 9. Pin soldering temperature limit is for 10 seconds maximum duration. Not designed for immersion soldering. Exceeding these limits may cause malfunction or permanent damage to the device. 10. Freescale’s Package Reflow capability meets Pb-free requirements for JEDEC standard J-STD-020C. For Peak Package Reflow Temperature and Moisture Sensitivity Levels (MSL), Go to www.freescale.com, search by part number [e.g. remove prefixes/suffixes and enter the core ID to view all orderable parts. (i.e. MC33xxxD enter 33xxx), and review parametrics. Table 3. Maximum Ratings (continued) All voltages are with respect to VSS unless otherwise noted. Exceeding these ratings may cause a malfunction or permanent damage to the device. Ratings Symbol Value Unit |
