VSS ............... -0.3 to (VDD+0.3)V Maximum Junction Temperature, TJ ............Internally Limited Storage temperature .....................................-65°C to +150°C ESD protection on all pins Human Body Model (1.5 kW in Series with 100 pF) ......≥ 4kV Machine Model (200pF, No Series Resistance) ..............400V † Notice: Stresses above those listed under “Maximum Ratings” may cause permanent damage to the device. This is a stress rating only and functional operation of the device at those or any other conditions above those indicated in the operational listings of this specification is not implied. Exposure to maximum rating conditions for extended periods may affect device reliability. DC CHARACTERISTICS Electrical Specifications: Unless otherwise indicated, all limits apply for VDD= [VREG(typ.) + 0.3V] to 6V, TA = -40°C to +85°C. Typical values are at +25°C, VDD = [VREG (typ.) + 1.0V] Parameters Sym Min Typ Max Units Conditions Supply Input Supply Voltage VDD 3.75 — 6 V Supply Current ISS — 1000 1500 µA Charging — 50 100 µA Standby (CE = VSS) — 1.2 5 µA Shutdown (VDD < VBAT - 100 mV) Voltage Regulation (Constant Voltage Mode) Regulated Output Voltage VREG —4.20 — V VDD=[VREG(Typ)+1V] IOUT=10 mA Output Voltage Tolerance VRTOL -1 — +1 % TA=-5°C to +55°C Line Regulation |(ΔVBAT/VBAT) / ΔVDD| — 0.09 0.30 %/V VDD=[VREG(Typ)+1V] to 6V IOUT=10 mA Load Regulation |ΔVBAT/VBAT| — 0.09 0.30 % IOUT=10 mA to 50 mA VDD=[VREG(Typ)+1V] Supply Ripple Attenuation PSRR — 52 — dB IOUT=10 mA, 10 Hz to 1 kHz —47 — dB IOUT=10 mA, 10 Hz to 10 kHz —22 — dB IOUT=10 mA, 10 Hz to 1 MHz Current Regulation (Fast Charge Constant-Current Mode) Fast Charge Current IREG — 85 — mA MCP73811 - PROG = Low Regulation — 450 — mA MCP73811 - PROG = High — 50 — mA MCP73812 - PROG = 20 k Ω — 100 — mA MCP73812 - PROG = 10 k Ω — 500 — mA MCP73812 - PROG = 2 k Ω Charge Current Tolerance IRTOL -10 — +10 % TA=-5°C to +55°C Pass Transistor ON-Resistance ON-Resistance RDSON — 400 — m Ω VDD = 3.75V, TJ = 105°C Battery Discharge Current Output Reverse Leakage IDISCHARGE Current — 0.5 2 µA Shutdown (VDD < VBAT - 100 mV) |
