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: Currents are positive into, negative out of the specified terminal. Consult Packaging Section of Data Book for thermal limitations and considerations of packages. All voltages are referenced to GND. electrical characteristics, TA = –20°C to 70°C, all voltages are with respect to BNEG (unless otherwise stated) state transition threshold PARAMETER TEST CONDITIONS MIN TYP MAX UNITS UCC3952–1 4.15 4.20 4.25 V Normal to overcharge voltage UCC3952–2 4.20 4.25 4.30 V V(OV) Normal to overcharge voltage UCC3952–3 4.25 4.30 4.35 V UCC3952–4 4.30 4.35 4.40 UCC3952–1 3.85 3.90 3.95 V Overcharge to normal recovery UCC3952–2 3.90 3.95 4.00 V V(OVR) Overcharge to normal recovery voltage UCC3952–3 3.95 4.00 4.05 V g UCC3952–4 4.00 4.05 4.10 V(UV) Normal to undercharge 2.25 2.35 2.45 V V(UVR) Undercharge to normal recovery 2.55 2.65 2.75 V td(OD) Overcharge delay time 10 25 40 ms short circuit protection PARAMETER TEST CONDITIONS MIN TYP MAX UNITS I(THLD) Discharge current limit PACK+ = 3.7 V 3.0 6.0 A td(DLY) Discharge current delay PACK+ = 3.7 V, II = 6 A 1 3.0 ms R(RESET) Discharge current reset resistance PACK+ = 3.7 V 7.5 M Ω bias PARAMETER TEST CONDITIONS MIN TYP MAX UNITS IDD Supply current V(UV) < V(PACK) < V(OV) 5 8 µA IDD(OV) Operating supply current in overvoltage V(OV) < V(PACK) 11 24 µA I(SD) Shutdown current V(PACK) = 2.0 V 2.5 µA V(min) Minimum cell voltage when all circuits are fully functional 1.7 V td(OV) Overvoltage delay time 1 2 s |
