API9221 CAR/WALL or USB SUPPLY INPUT LITHIUM BATTERY CHARGER with OVP USB BYPASS and 10mA LDO Description Pin Assignments (Top View) The PPR pin indicates to a host controller that a safe and valid supply is connected to either VUSB or VDC. The higher charge current option from VDC will take priority if both supplies are connected. The host controller can control the state of charging via the enable pin EN . The API9221 implements the constant current/constant voltage (CC/CV) charge algorithm for Lithium based battery cells. The connected cell will be charged to 4.2V with an accuracy of 1% over the entire temperature range. The termination current is programmable via an external resistor, RIMIN. The CHG pin indicates when the termination current is reached, and is reset by EN , power off, or battery below 3.9V. The maximum charge current can be programmed independently via the resistors RIUSB and RIVDC. The API9221 comes with several protection features. To prevent system damage, the VUSB pin uses over voltage protection (OVP) at 5.4V, and the VDC OVP is at 6.9V. Above these levels, the non-operating device is protected against damage up to 28V. For control and system start-up the API9221 has a current limited linear regulator. To protect the chip against excessive power dissipation, temperature monitoring is integrated, which folds back the current to a safe level. As the temperature rises, this foldback begins at 125°C without completely interrupting charging.

Before charging can begin, one of the two input voltages must also exceed the battery voltage enough to overcome the input-output comparator offset. When one The battery charge function is disabled when the EN input is pulled to logic HIGH. This normally requires an external pull-up resistor connected to the system microcontroller I/O power supply. The API9221 has an internal resistor connected from this pin to GND, typically 600kΩ. In many applications a suitable pull-up resistor value is 100kΩ. When EN is pulled LOW or left open circuit, charging is enabled as described below. There are two open-drain logic outputs, PPR and CHG . Each of these can use an external pull-up resistor to an appropriate supply such as the microcontroller I/O supply, or can be left open circuit. A suitable value is 100kΩ. Alternatively these can each be used to drive an indicator LED up to a maximum of 10mA. The output PPR is LOW when a valid power supply voltage is present at the VDC input or at the VUSB input, of the supplies satisfies these conditions, and EN is LOW, charging begins regardless of the state of the other supply. The valid input conditions are: for VDC: VPOR < VDC < OVPVDC and VDC > VBAT +VOSHC for VUSB: VPOR < VUSB < OVPVUSB and VUSB > VBAT + VOSHC where VPOR is the rising power-on threshold voltage, and VOSHC is the rising input offset voltage relative to VBAT. All these threshold voltages have defined hysteresis. When the charge current falls below IMIN, CHG goes HIGH (provided it has an external pull-up). This state is latched and is not re-set until one of the following events occurs: 1. EN is driven HIGH and LOW again 2. The active supply is removed and re-applied 3. VBAT falls below the re-charge threshold of 3.9V (nominally) independent of EN . One of the two input voltages must be greater than the power-on threshold and less than the overvoltage protection threshold. The output CHG is LOW when the battery is charging, but only until the End-of-Charge (EOC) condition is reached. Together with other conditions as described below, the voltage at the battery connection BAT is used to control the charging current. In the EOC state, CHG is HIGH to indicate that the charging phase has completed and the battery voltage has reached 4.2V (± 1%). In this state, the charger remains active and is able to supply load current and top up the battery as necessary. CHG may be re-set as described below under Charge Conditions. Auxiliary Outputs The USB_BYP and VDC_LDO outputs are available independently of the EN input state. This allows a host controller to power up initially. USB Bypass, USB_BYP The output USB_BYP provides power from the USB input when a valid power supply voltage is present at the VUSB input. It is current limited to 400mA (nominally). It is therefore safely limited in current and voltage within the USB standard. VDC Low dropout regulator VDC_LDO This output provides a regulated 4.94V supply, up to 10mA, when a valid power supply voltage is present at the VDC input. API9221 Document number: DS32204 Rev. 2 - 2 Note that the outputs, BAT, USB_BYP and VDC_LDO are reverse current protected. If an external voltage higher than the supply voltage is connected to one of these outputs, that output will be disabled. Charging from Adapter Power (VDC pin) The battery can be charged from an AC powered wall adapter or in-car adapter at a current of up to 1.2A using this input pin. The maximum charge current is set by an external resistor, RIVDC connected between the IVDC and GND pins. If VDC is greater than the power-on threshold voltage (VPOR) and less than the over-voltage protection threshold (OVPVDC), the battery will begin to charge at a rate dependent on the battery voltage. When VDC input is as recommended, (4.5V to 6.7V), no charge current is drawn from the VUSB input as VDC takes precedence. Input operation below 4.5V is also possible, but the charging rate may be affected. The resistor RIVDC determines the charge current according to IVDC = 6820 RIVDC Amp For example, a resistor value of 13kΩ sets a charge current of 0.525A. The recommended IVDC setting is 100mA to 1200mA. 8 of 15 www.diodes.com November 2011 © Diodes Incorporated API9221 CAR/WALL or USB SUPPLY INPUT LITHIUM BATTERY CHARGER with OVP USB BYPASS and 10mA LDO Functional Characteristics (cont.) Charging from Adapter Power (VDC pin) (cont.) NEW PRODUCT The maximum charge current available may be otherwise limited by the car/wall adapter current limit, by thermal protection within the API9221, or by the rDS(ON) of the FET in the VDC charging path. For example, if IVDC is set to 1A, there is a voltage drop of 0.6V due the typical rDS(ON) of 600mΩ at room temperature. Therefore, the voltage at the VDC input must be at least 4.8V to charge the battery to 4.2V in the minimum time. Charging from USB Power (VUSB pin) The battery can be charged at a current of up to 0.5A from this pin. In this case the maximum available charge current is set by an external resistor RIUSB connected between the IUSB and GND pins. If VUSB is greater than the power-on threshold voltage (VPOR) and less than the over-voltage protection threshold (OVPVUSB), the battery will begin to charge at a rate dependent on the battery voltage. The resistor RIUSB resistor determines the charge current according to 6820 RIUSB End-of-Charge Current During charging, as the battery voltage approaches the regulated value of 4.2V, the charging current will begin to decrease. Eventually the charging current settles to a value just low enough to maintain the regulated voltage. When the current becomes less than the End-of-Charge threshold current, IMIN, the logic output CHG goes HIGH. The threshold current is set by an external resistor connected between the IMIN and GND pins. This is independent of whether the VDC or VUSB input is valid. The VDC input is safe from damage up to 28V. IUSB = When the battery voltage reaches VMIN, the charge current increases to 100% of the available charge current. The resistor at IMIN determines the EOC threshold current according to IMIN = 550 RIMIN Amp For example, a resistor value of 10kΩ sets the EOC threshold current to 55mA. Accuracy When the constant voltage phase has been reached, the battery is charged to 4.2V ±1%. This is the maximum error over the ambient temperature range from -40°C to +85°C. Amp For example, a resistor value of 22kΩ sets a charge current of 0.31A. The recommended IUSB setting is 46.5mA to 465mA. The maximum charge current available may be otherwise limited by the external USB current limit, or by thermal protection within the API9221. The RDS(ON) of the FET in the USB charging path is typically 600mΩ at room temperature. At the IUSB limit of 465mA, there is a voltage drop of nearly 0.3V. Therefore, the voltage at the VUSB input must be at least 4.5V to charge the battery to 4.2V in the minimum time. Fault Summary and Protection Overvoltage protection: If VDC is greater than OVPVDC (6.9V), the VDC charging path is turned off until VDC falls below OVPVDC - HOVPVDC, where HOVPVDC is the OVP hysteresis. Similarly, if VUSB is greater than OVPVUSB (5.4V), the USB charging path is turned off until VUSB falls below OVPVUSB – HOVPVUSB. USB_BYP current limit: The USB_BYP load current is limited to 400mA (nominally). USB_BYP reverse blocking: If the voltage at USB_BYP is greater than VUSB, the USB bypass path is turned off. The VUSB input is safe from damage up to 28V. Trickle Charge When the battery voltage is below the Preconditioning Threshold, VMIN, the charger is in the Trickle Charge state and the charge current is limited to 18% of the available charge current set by RIVDC or RIUSB. If the USB charge current is programmed to a value less than the VDC trickle charge, then this value of the USB current is used in trickle mode (no derating). API9221 Document number: DS32204 Rev. 2 - 2 BAT reverse blocking: If the battery voltage is greater than either VDC or VUSB, the relevant charge path is turned off. VDC_LDO reverse blocking: If the voltage at VDC_LDO is greater than VDC, the linear regulator is turned off. Thermal protection: When the junction temperature reaches 125°C, a current foldback circuit is activated. This effectively limits the power dissipation to a safe level. 9 of 15 www.diodes.com November 2011 © Diodes Incorporated API9221 CAR/WALL or USB SUPPLY INPUT LITHIUM BATTERY CHARGER with OVP USB BYPASS and 10mA LDO Functional Characteristics (cont.)
