6 / 60 page ![]() 4 Technical Data 4.1 Absolute Maximum Ratings Absolute maximum ratings are those values beyond which damage to the device may occur. Functional operation under these conditions is not implied. All voltages are referenced to GND unless otherwise specified. Table 2. Absolute maximum ratings Symbol Parameter Value Unit VVPLUS, VCQ, VDIO Pin Voltage (steady-state) - 35 to + 35 V Pin Voltage (during surge pulse transient with 500 Ω coupling, ISURGE < ± 3 APK) - 45 to + 45 VV5V 5V voltage pin - 1 to 7 V VV3V3 3.3V voltage pin - 1 to 5 V VDIG, VLED1, VLED2 Digital pins (SPI, CTLD, INT, VDIG) and LED pins - 1 to 7 V VESD Electrostatic protection (HBM) 2 kV PD Power Dissipation Internally limited W TLEAD Soldering temp. (20-40sec, cf. JEDEC J-STD-020C) 260 °C TSTOR Storage Temperature Range -40 to 150 °C Operation above the absolute maximum ratings may lead to instantaneous device failure. Operation of the L6364 between the operating ratings and the absolute maximum ratings leads to a reduced operating lifetime. 4.2 Thermal Characteristics Table 3. Thermal data Symbol Parameter Value Unit QFN20L CSP19 Rth(JA) Thermal resistance junction-ambient on evaluation boards(1) 54 80 °C/W Thermal resistance junction-ambient as per JEDEC specification (JESD51-7) (2) 38 43.4 1. 2s, FR4, Cu thickness = 35 μm 2. 2s2p, FR4 under still air conditions 4.3 Recommended operating conditioning Table 4. Recommended operating conditions Symbol Parameter Min. Typ. Max. Unit IQUIES Operating current supply, no pin currents, DC-DC enables 3.0 3.5 mA IQUIES_START Operating current supply on pin VPLUS during startup 10 mA VSUP VPLUS supply voltage, IV3v3= 50 mA, (DC-DC disabled) 4.5 24 35 V L6364 Technical Data DS13363 - Rev 4 page 6/60 |
