MP2607 Li + LINEAR Charger WithSystem Power Path Management The Future of Analog IC Technology DESCRIPTION FEATURES MP2607 is a highly-integrated single-cell LiIon/Li-Polymer battery charger with system power path management function. It takes input from either AC adapter or USB port to supply the system and charge the battery independently. The charger section features trickle charge, high-accuracy constant current (CC) and constant voltage (CV) regulation, charge termination and charge status. • The system power path management function ensures continuous supply to the system by automatically selecting the input, the battery or both to power the system. This section features a low drop-out regulator from input to system, and a 50mΩ switch from battery to system. Power path management separates charging current from system load, which allows proper charge termination and keeps battery stay fullycharged. It also allows instantaneous power up of system with a deeply discharged battery.

The maximum allowable continuous power dissipation at any ambient temperature is calculated by PD(MAX)=(TJ(MAX)TA)/ θJA. Exceeding the maximum allowable power dissipation will cause excessive die temperature, and the regulator will go into thermal shutdown. Internal thermal shutdown circuitry protects the device from permanent damage. 3) The device is not guaranteed to function outside of its operating conditions. 4) Measured on JESD51-7 4 layers board. www.MonolithicPower.com MPS Proprietary Information.

For AC: Vout = 5V Coarse current limit = 2A SYS 2. For USB: Vout=VIN Accurate current limit set internally to 450mA typ. MODE SYSTEM COMP SYS2V, or no VIN High High NTC Temperature Sensor The NTC pin allows MP2607 to sense the ambient temperature using the Negative Thermal Coefficient (NTC) thermistor usually available in the battery pack to ensure a safe operating environment of the battery. A resistor with appropriate value should be connected from VIN to NTC and the NTC resistor parallel connected a regular resistor is connected form NTC pin to ground. The voltage on NTC pin is determined by the resistor divider whose divide ratio depends on the ambient temperature. MP2607 internally sets a pre-determined upper and lower bound of the divide ratio. If NTC pin voltage falls out of this range which means the temperature is outside the safe operating range, MP2607 will stop charging and report it on status pins. Charging will automatically resume after the temperature falls back into the safe range. Enable Enable of MP2607 is controlled by pulling CEB pin below 0.3V. Pulling CEB pin above 2V will put MP2607 in sleep mode, which disables power path management and battery charger. In sleep mode, the N-channel switch between BATT and SYS is fully on to maintain system supply. Battery under-voltage and current limit are kept alive to provide safeguard. www.MonolithicPower.com MPS Proprietary Information. Patent Protected.

All Rights Reserved. 12 MP2607 – LI-ION CHARGER WITH POWER PATH MANAGEMENT APPLICATION INFORMATION COMPONENT SELECTION Battery Charging Current The charging current of MP2607 is programmable using an external resistor RCHG at ICHSET pin: ICHG 1.260V = 1800 × R CHG (Ω) Where 1.260V is an internal reference voltage for ICHSET programming. Typically RCHG is chosen between 1.51kΩ (1.50A ICHG) and 7.5kΩ (300mA ICHG). However, due to current limit constraint at the input source, either adapter or USB port input, the charging current could be less than above calculated value if system load demand is high. MP2607 will always ensure the sum of system load current and charging current complies with source current limit, with system load has the priority. Especially for USB mode, when system load exceeds the source current limit, charging is actually stopped and battery is pulled in to supplement the system load. When using USB port as input source, if the charging current is set higher than USB port current limit IUSB_MAX, then the real charging current will not be higher than USB current limit and could be reduced further if system draws any load. End of Charge Threshold Current The end of charge threshold current is set internally to be at 10% of ICHG: IEOC = 180 × 1.260V R CHG (Ω) Where 1.260V is an internal reference voltage and RCHG is the programming resistor at ICHSET pin. When the charging current falls below IEOC in CV charge mode, MP2607 will terminate charge, and latch the status pin to indicate the end of charge. MP2607 Rev. 1.03 5/18/2015 Trickle Charge Current When the battery voltage is below the minimum battery voltage VTH_TRKL (defined in the electrical characteristics table), the charger operates in a trickle/preconditioning mode, where the charging current is typically 7.5% of the programmed charge current ICHG. ITRKL = 150 × 1.260V RCHG (Ω) Timer for Charge Termination MP2607 has a built-in timer to terminate the charge if the timer times out, no matter whether IEOC is reached or not. And once the battery is charged full, the timer is reset. This timer is programmable using an external capacitor CTMR at TMR pin, to allow user adjust to different battery capacity. The timer can be calculated as: τTMR_F = 1.1hours × 2μA + 1A/36000 CTMR × 2μA + ICHG /36000 1μF The timer period is strictly inversely proportional to the real charging current (either in power path state or CV charge mode), the sink and source current of CTMR is 2μA + Ichg / 36000 . So, the trickle charge timer can be calculated based on the τTMR_F: τ TMR_T 215 2μA + ICHG /36000 = τ TMR_F × 17 × 2 2μA + ITRKL /36000 Due to the power path management function, the real charging current usually varies during the whole charging process, thus MP2607 automatically takes into account this variation and adjust the timer time out accordingly. Basically the timer increases the same proportion as the charging current decreases. If the charging is stopped due to high system load, the timer is temporarily suspended. In this way, the actual energy delivered to the battery, which is charging current multiplying the charging time, remains constant. The time out operation will set the charger into suspended state and be reported at the status output pins. To clear the time out status, one has to recycle the chip enable pin or IN supply. www.MonolithicPower.com MPS Proprietary Information. Patent Protected.

The two resistors RT1 and RT2 allow the high temperature limit and low temperature limit to be programmed independently. In another word, MP2607 can fit most type of NTC resistor and different temperature operation range requirement with the two extra resistors. RT1 and RT2 values depend on the type of the NTC resistor: RT2 = 0.3 × RNTCH × RNTCL 0.12 × RNTCL − 0.42 × RNTCH RT1 = 0.667 × (RT2 / /RNTCL ) RNTCH is the value of the NTC resistor at high temperature of the required temperature operation range, and RNTCL is the value of the NTC resistor at low temperature.
