2 / 51 page Absolute maximum ratings & operating conditions TS4956 2/51 1 Absolute maximum ratings & operating conditions Table 1. Absolute maximum ratings (AMR) Symbol Parameter Value Unit VCC Supply voltage (1) 1. All voltage values are measured with respect to the ground pin. 6V Vi Input voltage (2) 2. The magnitude of input signal must never exceed VCC + 0.3V / GND - 0.3V GND to VCC V Toper Operating free air temperature range -40 to + 85 °C Tstg Storage temperature -65 to +150 °C Tj Maximum junction temperature 150 °C Rthja Thermal resistance junction to ambient (3) 3. Device is protected in case of over temperature by a thermal shutdown activated at 150°C. 200 °C/W Pdiss Power dissipation Internally limited(4) 4. Exceeding the power derating curves during a long period may involve abnormal operating conditions. ESD Susceptibility - human body model(5) 5. Human body model, 100 pF discharged through a 1.5 k Ω resistor, into pin to VCC device 2kV Susceptibility - machine model 150 V Latch-up Latch-up immunity 200 mA Lead temperature (soldering, 10sec) 260 °C Table 2. Operating conditions Symbol Parameter Value Unit VCC (1) 1. For proper functionality of I2C bus, VCC pins must not be grounded. ESD protection diodes ground data and clock wires and cause dysfunction of I2C bus in this condition. Supply voltage 2.7 to 5.5V V RL Load resistor Speaker/BTL output (modes 1,2,7) Headphone, MLO output (modes 3,4,5,6,) ≥8 ≥16 Ω CL Load capacitor RL = 8Ω to 100Ω (Speaker/BTL output - modes 1,2,7) RL = 16Ω to 100Ω (Headphone, MLO output - modes 3,4,5,6) RL > 100Ω 500 400 100 pF Rthja Flip-chip thermal resistance junction to ambient 90(2) 2. With heat sink surface 120mm2 °C/W Table 3. I²C electrical characteristics Symbol Parameter Value Unit I2CVCC I2C supply voltage(1) 1. Must be less or equal than power supply voltage VCC of the device 2.7V to 5.5V V VILl Maximum low level input voltage on pins SDA, SCL 0.3 I2CVCC V VIH Minimum high level input voltage 0.7 I2CVCC V IIN Maximum input current (pins SDA, SCL), 0.4V < Vin < 4.5V 10 µA FSCL SCL maximum clock frequency 400 kHz Vol Max low level output voltage, SDA pin, Isink = 3mA 0.4 V |
