Electrical Characteristics Limits in standard type are for T
J = 25°C only; limits in boldface type apply over the
junction temperature range of -40°C to +125°C. Minimum and Maximum limits are guaranteed through test, design, or statistical
correlation. Typical values represent the most likely parametric norm at T
J = 25°C, and are provided for reference purposes only.
Unless otherwise specified, the following conditions apply: V
VIN = 48V, VVCCDIS = 0V, RT = 25k, no load on LO & HO.
