ABSOLUTE MAXIMUM RATINGS
These are stress ratings only and functional operation of
the device at these ratings or any other above those
indicated in the operation sections of the specifications
below is not implied. Exposure to absolute maximum
rating conditions for extended periods of time may affect
reliability.
VCCD, LDO5, LDO3_3, GLx, VOUTx ............. -0.3V to 7.0V
ENABLE, 5V_EXT ....................................... -0.3V to 7.0V
GPIO0/1, SCL, SDA................................................ 6.0V
PSIOs Inputs, BFB .................................................. 18V
DVDD, AVDD ........................................................ 2.0V
VCC ...................................................................... 28V
LX# .............................................................-1V to 28V
BSTx, GHx.................................................... VLXx + 6V
Storage Temperature .............................. -65°C to 150°C
Power Dissipation ................................ Internally Limited
Lead Temperature (Soldering, 10 sec).................... 300°C
ESD Rating (HBM - Human Body Model) .................... 2kV
OPERATING RATINGS
Input Voltage Range VCC ...............................5.5V to 25V
Input Voltage Range VCC = LDO5 ................4.75V to 5.5V
VOUT1, 2, 3, 4 ...................................................... 5.5V
Junction Temperature Range ....................-40°C to 125°C
JEDEC Thermal Resistance θJA ..........................30.2°C/W
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, VCC = 5.5V to 25V, 5V EXT open. Note that in cases where there is a
discrepancy in values shown in this section and other sections of the datasheet, the values in the Electrical Specification
section shall be deemed correct and supersede the other values.
