These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTE 1: All voltages are with respect to GND. DISSIPATION RATING TABLE PACKAGE TA < 25°C POWER RATING DERATING FACTOR ABOVE TA = 25°C TA = 70°C POWER RATING TA = 85°C POWER RATING DBV 309 mW 3.1 mW/ °C 170 mW 123 mW D 568 mW 5.7 mW/ °C 313 mW 227 mW recommended operating conditions MIN MAX UNIT Input voltage, VI(INx) 2.7 4 V Input voltage, VI at EN and EN 0 4 V Continuous output current, IO(IN1) 500 mA Continuous output current, IO(IN2) 100‡ mA Operating virtual junction temperature, TJ –40 85 °C ‡ The device can deliver up to 220 mA at IO(IN2). However, operation at the higher current levels will result in greater voltage drop across the device, and greater voltage droop when switching between IN1 and IN2. electrical characteristics over recommended operating junction temperature range, VI(IN1) = V(IN2) = 3.3 V, IO = rated current (unless otherwise noted) power switch PARAMETER TEST CONDITIONS† MIN TYP MAX UNIT IN1 OUT TJ = 25°C 250 m Ω rDS( ) On state resistance IN1-OUT TJ = 85°C 300 375 m Ω rDS(on) On-state resistance IN2 OUT TJ = 25°C 1.3 Ω IN2-OUT TJ = 85°C 1.5 2.1 Ω † Pulse-testing techniques maintain junction temperature close to ambient termperature; thermal effects must be taken into account separately. |
