MAX20480 Four- to Seven-Input Automotive Power-System Monitor Family
Absolute Maximum Ratings
VDD to GND.. -0.3V to +6V ADDR to GND... -0.3V to VDD + 0.3V EN0, EN1 to GND .. -0.3V to +6V Continuous Power Dissipation (TA = +70°C) .. IN1-IN5 to GND .. -0.3V to +6V 16-TQFN (derate 20.8mW/°C > 70°C)...1666.7mW INP6-INP7 to GND ... -0.3V to +6V Operating Temperature...-40ºC to +125ºC INM to GND ... -0.3V to 0.3V Junction Temperature ... +150ºC RESET to GND... -0.3V to +6V Storage Temperature Range ..-65ºC to +150ºC SDA, SCL to GND .. -0.3V to +6V Lead Temperature Range... +300ºC Stresses beyond those listed under “Absolute Maximum Ratings” 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 the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
Package Information 16-TQFN-EP
Package Code T1633Y+5 Outline Number 21-100150 Land Pattern Number 90-100064
THERMAL RESISTANCE, FOUR-LAYER BOARD
Junction-to-Ambient (θJA) 44.5°C/W Junction-to-Case Thermal Resistance (θJC) 5.9°C/W For the latest package outline information and land patterns (footprints), go to www.maximintegrated.com/packages. Note that a “+”, “#”, or “-” in the package code indicates RoHS status only. Package drawings may show a different suffix character, but the drawing pertains to the package regardless of RoHS status. Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer board. For detailed information on package thermal considerations, refer to www.maximintegrated.com/ thermal-tutorial.
