Stresses in excess of these ratings can cause permanent damage to the device. Functional operation of the device at conditions beyond those indicated in the operational sections of this data sheet is not implied. 1.4 ESD Warning ESD (electrostatic discharge) sensitive device. Electrostatic charges can readily accumulate on test equipment and the human body in excess of 4000 Volts. This energy can discharge without detection. Although the IX6611 features proprietary ESD protection circuitry, permanent damage might be sustained if subjected to high energy electrostatic discharges. Proper ESD precautions are recommended to avoid performance degradation or loss of functionality. 4 PRELIMINARY R00A IX6611 1.5 Electrical Characteristics TA=-40°C to +125°C unless otherwise noted. 1.5.1 Thermal Characteristics Parameter Thermal resistance, junction to ambient 1.5.2 Symbol Rating Units JA 41 °C/W Power Supply Terminals Parameter Symbol Conditions Min Typ Logic power supply voltage range VCC VCC-VCOM 13 15 Logic power supply voltage range VEE VEE-VCOM -10 -5 0 V Output driver positive power supply voltage range PVCC PVCC-VCOM 13 15 25 V Output driver negative power supply voltage range PVEE PVEE-VCOM -10 -5 0 V Static power supply current ICCQ - 3 5 - 0.2 0.5 VCC= PVCC=15V, VEE= PVEE= -5V No load, static output condition ICOMQ IEEQ Dynamic power supply current ICC ICOM IEE 1.5.3 VCC= PVCC=15V, VEE= PVEE= -5V, CL=10nF Normal mode, FOUT=50kHz Max Units 25 V - 3 5 - 15 20 - 0.2 0.5 - 15 20 mA mA VDD Regulator (Logic Supply) VCC=PVCC=15V, VEE=PVEE= -5V.
