(1)

All hot and cold limits are specified by correlating the electrical characteristics to process and temperature variations and applying

statistical process control.

(2)

The junction temperature (TJ in °C) is calculated from the ambient temperature (TA in °C) and power dissipation (PD in Watts) as follows:

TJ = TA + (PD • θJA) where θJA (in °C/W) is the package thermal impedance provided in Thermal Information.

6.5 Electrical Characteristics

Typical values correspond to TJ = 25°C. Minimum and maximum limits are based on TJ = –40°C to +125°C. VIN = 12 V

(unless otherwise noted).
