DS21984E-page 5 MCP73831/2 TEMPERATURE SPECIFICATIONS AC CHARACTERISTICS Electrical Specifications: Unless otherwise indicated, all limits apply for V DD = [VREG (typical) + 0.3V] to 12V, TA = -40°C to +85°C. Typical values are at +25°C, VDD = [VREG (typical) + 1.0V] Parameters Sym. Min. Typ. Max. Units Conditions UVLO Start Delay tSTART —— 5 ms VDD Low-to-High Constant-Current Regulation Transition Time Out of Preconditioning tDELAY —— 1 ms VBAT < VPTH to VBAT > VPTH Current Rise Time Out of Preconditioning tRISE —— 1 ms IOUT Rising to 90% of IREG Termination Comparator Filter tTERM 0.4 1.3 3.2 ms Average IOUT Falling Charge Comparator Filter tCHARGE 0.4 1.3 3.2 ms Average VBAT Status Indicator Status Output turn-off tOFF —— 200 µ sISINK = 1 mA to 0 mA Status Output turn-on tON —— 200 µ sISINK = 0 mA to 1 mA Electrical Specifications: Unless otherwise indicated, all limits apply for V DD = [VREG (typical) + 0.3V] to 12V. Typical values are at +25°C, VDD = [VREG (typical) + 1.0V] Parameters Sym. Min. Typ. Max. Units Conditions Temperature Ranges Specified Temperature Range TA -40 — +85 °C Operating Temperature Range TJ -40 — +125 °C Storage Temperature Range TA -65 — +150 °C Thermal Package Resistances 5-Lead, SOT-23 θ JA — 230 — °C/W 4-Layer JC51-7 Standard Board, Natural Convection (Note 2) 8-Lead, 2 mm x 3 mm, DFN θ JA — 76 — °C/W 4-Layer JC51-7 Standard Board, Natural Convection (Note 1) Note 1: This represents the minimum copper condition on the PCB (Printed Circuit Board). 2: With large copper area on the PCB, the SOT-23-5 thermal resistance ( θ JA ) can reach a typical value of 130°C/W or better. |
