3. CHARACTERISTICS AND SPECIFICATIONS
3.1 Electrical Characteristics
Typical characteristics conditions:
• TA = 25 °C, VDD = 12V, GND = 0 V
• All voltages are measured with respect to GND.
• Unless otherwise specified, all currents are positive
when flowing into the IC.
Minimum/Maximum characteristics conditions:
• TJ = -40°C to +125 °C, VDD = 11V to 17V, GND = 0 V
