The bq2420x series offer integrated powerFET, high-accuracy voltage regulation, temperature monitoring, charge status, and charge termination, in a single monolithic device. The bq2420x is designed to work with a current-limited wall-mount transformer and therefore does not provide any current regulation. However, these devices offer a fixed internal current limit to prevent damage to the internal powerFET. A time-limited pre-conditioning phase is provided to condition deeply discharged cells. Once the battery reaches the charge voltage, the high accuracy voltage regulation loop takes over and completes the charge cycle. Charge is terminated based on minimum current. An internal charge timer provides a backup safety for charge termination. Other standard features include an automatic sleep mode activated when VCC falls below the battery voltage and a recharge feature activated when the battery voltage falls below the VRCH threshold. In addition to the standard features, the core product provides two additional enhancements: temperature monitoring and status display. The temperaturesense circuit continuously measures battery temperature using an external thermistor and inhibits charge until the battery temperature is within the user-defined thresholds. The STAT pin indicates three conditions of operation of the charger. These conditions are charge-in-progress, charge complete, and fault. This output can be used to drive an LED or an interface to a microcontroller. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

Low Dropout Single-Cell Li-Ion/Li-Pol Charger FUNCTIONAL DESCRIPTION The bq2420x supports a precision Li-Ion or Li-Pol charging system suitable for single-cells with either coke or graphite anodes. Figure 5 shows an application schematic and Figure 6 shows the typical charge profile. TEMPERATURE QUALIFICATION (bq24200 and bq24202 only) The bq24200 and bq24201 continuously monitors battery temperature by measuring the voltage between the TS and VSS pins. A negative- or a positive-temperature coefficient thermistor (NTC, PTC) and an external voltage divider typically develop this voltage (see Figure 5). The bq24200 and bq24201 compare this voltage against the internal V(TS1) and V(TS2) thresholds to determine if charging is allowed (see Figure 7). The temperature sensing circuit is immune to any fluctuation in Vcc since both the external voltage divider and the internal thresholds are referenced to Vcc. Once a temperature outside the V(TS1) and V(TS2) thresholds is detected the bq24200 and bq24201 immediately suspend the charge. The bq24200 and bq24201 suspend the charge by turning off the power FET and holding the timer value (i.e., timers are NOT reset). Charge is resumed when the temperature returns to the normal range. 8 Submit Documentation Feedback Copyright © 2001–2008, Texas Instruments Incorporated Product Folder Link(s): bq24200, bq24201 bq24202, bq24203 bq24204, bq24205 bq24200, bq24201 bq24202, bq24203 bq24204, bq24205 www.ti.com SLUS501C – OCTOBER 2001 – REVISED MARCH 2008 Figure 6.

RT1 or RT2 can be omitted If only one temperature (hot or cold) setting is required. Applying a voltage between the VTS1 and VTS2 thresholds to pin TS disables the temperature-sensing feature. Also applying a voltage between (VCC – 0.3 V) and Vcc suspends the charge and places the IC in the low-power standby mode. BATTERY PRE-CONDITIONING Figure 7 shows the operational flow chart for the bq2420x. Upon power-up, if the battery voltage is below the V(LOWV) threshold, the bq2420x applies a pre-charge current, I(PRECHG), to the battery. This feature revives deeply discharged cells. The bq2420x activates a safety timer, t(PRECHG), during the conditioning phase. If V(LOWV) threshold is not reached within the timer period, the bq2420x turns off the charger and enunciates FAULT on the STAT pin. In the case of a FAULT condition, the bq2420x reduces the current to I(DETECT). I(DETECT) is used to detect a battery replacement condition. Fault condition is cleared by POR or battery replacement. BATTERY CHARGE CURRENT Following a successful pre-conditioning, the bq2420x relies on an external current-limited supply to limit the charge current to the cell. The bq2420x continues this phase until the battery reaches the voltage regulation phase. During this phase (and all other phases of operation) in order to protect the integrated powerFET, the internal short circuit and thermal protection circuits are active. BATTERY VOLTAGE REGULATION The voltage regulation feedback is through the BAT pin. This input is tied directly to the positive side of the battery pack. The bq2420x monitors the battery-pack voltage between the BAT and VSS pins. The bq2420x is offered in two fixed-voltage versions: 4.1 V and 4.2 V. As a safety backup, the bq2420x also monitors the charge time in the voltage regulation mode. If taper current is not detected within this time period, t(CHG), the bq2420x turns off the charger and enunciates FAULT on the STAT pin. Fault condition is cleared by POR or battery replacement. Note that the safety timer is reset if the bq2420x is forced out of the voltage regulation mode. CHARGE TERMINATION AND RECHARGE The bq2420x monitors the charging current during the voltage regulation phase. Once the taper threshold, I(TAPER), is detected the bq2420x initiates the taper timer, t(TAPER). Charge is terminated after the timer expires. The bq2420x resets the taper timer in the event that the charge current returns above the taper threshold, I(TAPER). In addition to the taper current detection, the bq2420x terminates charge in the event that the charge current falls below the I(TERM) threshold. This feature allows for quick recognition of a battery removal condition.

This feature keeps the battery at full capacity at all times. SLEEP MODE The bq2420x enters the low-power sleep mode if the Vcc is removed from the circuit (i.e., the Vcc and IN pins are floating). For applications where these pins are not floating, placing a low-power 10 Ω (1/16 W) between the IN and VCC pins ensures the V(SLP) conditions are met (see Figure 9).This feature prevents draining the battery during the absence of VCC. Figure 9. Sleep Mode CHARGE ENABLE PIN The CE pin on bq24202, bq24203, bq24204 and bq24205 can be used to enable or suspend the charge. Charge is enabled if the voltage VIL(CE) is applied to the pin. Applying the VIH(CE) suspends the charge. During a charge suspend mode, the internal powerFET is turned off and all timers are reset. CHARGE STATUS OUTPUT The STAT pin on the bq2420x, indicates various conditions of operation. These conditions are summarized in Table 1. Table 1.

All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment. TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily performed. TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide adequate design and operating safeguards. TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI. Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions. Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements. Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use of any TI components in safety-critical applications. In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and requirements. Nonetheless, such components are subject to these terms. No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties have executed a special agreement specifically governing such use. Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
