Exposure to absolute maximum rating conditions for extended periods of time may affect reliability. VCCA, VCCD, LDOOUT, GLx, VOUTx............................ 6V VDD..................................................................... 2.0V VIN1, VIN2 ............................................................ 27V LXx..............................................................-1V to 27V LXx............................................................. -5V to -1V1 Logic Inputs, GPIOs, SDA, SCL................................... 6V BSTx, GHx.................................................... VLXx + 6V ESD Rating (HBM - Human Body Model) .................... 2kV Storage Temperature.............................. -65°C to 150°C Lead Temperature (Soldering, 10 sec) ................... 300°C OPERATING RATINGS Input Voltage Range.....................................5.5V to 25V Input Voltage VIN=VCCA ...........................4.75V to 5.5V Junction Temperature Range ....................-40°C to 125°C Thermal Resistance θJA ....................................24.3°C/W Note 1: 200ns Transient ELECTRICAL SPECIFICATIONS Specifications with standard type are for an Operating Junction Temperature of TJ = 25°C only; limits applying over the full Operating Junction Temperature range are denoted by a “•”. Minimum and Maximum limits are guaranteed 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 indicated, VIN1 = 4.75V to 25V, VIN2 = 4.75V to 25V.
