Electrical Specifications
VIN = 12V, VBOOST = VSUP = 15V, VON = 25V, VOFF = -8V, over-temperature from -40°C to +105°C, unless
otherwise stated. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise
specified. Temperature limits established by characterization and are not production tested. (Continued)
