U6083B_05 Datasheet, PDF (10/13 Pages) ATMEL Corporation – PWM Power Control IC with Interference Suppression

6. Electrical Characteristics (Continued)
T_amb = –40°C to +110°C, V_Batt = 9V to 16.5V, (basic function is guaranteed between 6.0V to 9.0V) reference point ground, unless
otherwise specified (see Figure 1-1 on page 2). All other values refer to pin GND (pin 2).
