OVP_SEL 10 I Logic-level control input for choosing the OUT overvoltage threshold. When OVP_SEL is low, V(OV_OUT_LOW) is active. When OVP_SEL is high, V(OV_OUT_HIGH) is active. STATUS 17 O Active-low open-drain output, asserted in load-detect conditions Thermal pad — — Thermal pad on the bottom of the package (1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. 6 Specifications 6.1 Absolute Maximum Ratings Voltages are with respect to GND unless otherwise noted (1) MIN MAX UNIT Voltage range CS, CTL1, CTL2, EN, FAULT, ILIM_HI, ILIM_LO, IN, IMON, OVP_SEL, STATUS –0.3 7 V DM_OUT, DP_OUT –0.3 5.7 BIAS, DM_IN, DP_IN, OUT –0.3 18 Continuous current DM_IN to DM_OUT or DP_IN to DP_OUT –100 100 mA OUT Internally limited Continuous output source current, ISRC ILIM_HI, ILIM_LO, IMON Internally limited A Continuous output sink current, ISNK FAULT, STATUS 25 mA CS Internally limited A Operating junction temperature, TJ –40 Internally limited °C Storage temperature,Tstg –65 150 °C (1) AEC Q100-002 indicates that HBM stressing shall be in accordance with the ANSI/ESDA/JEDEC JS-001 specification.
