6 / 32 page Absolute maximum ratings and operating conditions STCC2540 6/32 DocID024711 Rev 6 3 Absolute maximum ratings and operating conditions Stressing the device beyond the rating listed in Table 2: Absolute maximum ratings (AMR) may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated in Table 3: Operating conditions is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Table 2. Absolute maximum ratings (AMR) Symbol Parameter Value Unit VIN, VOUT Supply voltage -0.3 to 6.5 V VEN, VCTLx Logical input voltage -0.3 to 6.5 VFAULT, VCHARGING Pull-up voltage (FAULT, CHARGING) -0.3 to 6.5 VDP_OUT, VDM_OUT, VDP_IN, VDM_IN Data switch pin voltage to ground -0.3 to VIN +0.3 IDP_OUT, IDM_OUT, IDP_IN, IDM_IN Data switch current, switch ON ±50 mA IO(OUT) Maximum power switch output current, power switch ON Internally limited - IO(FAULT), IO(CHARGING) Logical output sink current 25 mA TSTG Storage temperature (VIN OFF) -55 to +150 °C TSLD Lead solder temperature for 10 seconds temperature (VIN OFF)(1) 260 Rthja Thermal resistance junction-to-ambient VFQFPN 16L(2) 60 °C/W Tj Maximum junction temperature (internally limited) -40 to TSTOP °C VESD(OUT, DP_IN, DM_IN) IEC61000-4-2 contact discharge (OUT, DP_IN, DM_IN pins) 8 kV VESD JEDEC human body model (all pins)(3) 2 JEDEC machine model (all pins) 200 V 1. Reflow at temperature of 255 to 260 °C for time < 30 seconds (total thermal budget not to exceed 180 °C for a period from 90 to 150 seconds). 2. Rth are typical values, given when mounted on a 4-layer PCB with vias. 3. Measured in recommended application circuit with 1 μF ceramic capacitor + 150 μF low ESR electrolytic capacitor connected between OUT and GND pins (see Figure 4: Typical application diagram). Table 3. Operating conditions Symbol Parameter Value Unit VIN Supply voltage 4.5 to 5.5 V TA Ambient operating temperature -40 to +85 °C TJ Junction operating temperature -40 to +125 |
