3 / 24 page LM34914 www.ti.com SNVS453B – MAY 2006 – REVISED MARCH 2013 Absolute Maximum Ratings (1) (2) VIN to RTN 44V BST to RTN 52V SW to RTN (Steady State) -1.5V BST to VCC 44V VIN to SW 44V BST to SW 14V VCC to RTN 14V SGND to RTN -0.3V to +0.3V Current out of ISEN See text SS to RTN -0.3V to 4V All Other Inputs to RTN -0.3 to 7V ESD Rating(3) Human Body Model 2kV Storage Temperature Range -65°C to +150°C JunctionTemperature 150°C (1) Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which operation of the device is intended to be functional. For specifications and test conditions, see Electrical Characteristics. (2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and specifications. (3) The human body model is a 100pF capacitor discharged through a 1.5k Ω resistor into each pin. Operating Ratings (1) VIN Voltage 8.0V to 40V Junction Temperature −40°C to + 125°C (1) Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which operation of the device is intended to be functional. For specifications and test conditions, see Electrical Characteristics. Electrical Characteristics Limits in standard type are for TJ = 25°C only; limits in boldface type apply over the junction temperature (TJ) range of -40°C to +125°C. Minimum and Maximum limits are specified through test, design, or statistical correlation. Typical values represent the most likely parametric norm at TJ = 25°C, and are provided for reference purposes only. Unless otherwise stated the following conditions apply: VIN = 12V, RON = 200kΩ (1) (2). Symbol Parameter Conditions Min Typ Max Units Start-Up Regulator, VCC VCCReg VCC regulated output Vin > 9V 6.6 7.0 7.4 V ICC = 0 mA, VIN-VCC dropout voltage 1.3 V VCC = UVLOVCC + 250 mV VCC output impedance VIN = 8V 155 Ω (0 mA ≤ ICC ≤ 5 mA) VIN = 40V 0.16 VCC current limit (3) VCC = 0V 11 mA UVLOVCC VCC under-voltage lockout VCC increasing 5.7 V threshold UVLOVCC hysteresis VCC decreasing 150 mV UVLOVCC filter delay 100 mV overdrive 3 µs IIN operating current Non-switching, FB = 3V 0.57 0.85 mA IIN shutdown current RON/SD = 0V 80 160 µA (1) For detailed information on soldering plastic WSON packages, visit www.ti.com/packaging. (2) Typical specifications represent the most likely parametric norm at 25°C operation. (3) VCC provides self bias for the internal gate drive and control circuits.
