Product Description
Battery Management ICs High Input Voltage,3A Single-Cell Battery Chargerwith NVDC Power Path Management
The SGM41519 is a battery charger and system power pathmanagement device with integrated converter and powerswitches for using with single-cell Li-Ion or Li-polymerbatteries. This highly integrated 3A device is capable of fastcharging and supports a wide input voltage range suitable forsmart phones, tablets and portable systems. I2Cprogramming makes it a very flexible powering and chargerdesign solution.
The device includes four main power switches: input reverseblocking FET (RBFET, Q1), high-side switching FET for Buckor Boost mode (HSFET, Q2), low-side switching FET for Buckor Boost mode (LSFET, Q3) and battery FET that controls theinterconnection of the system and battery (BATFET, Q4). Thebootstrap diode for the high-side gate driving is alsointegrated. The internal power path has a very low impedancethat reduces the charging time and maximizes the batterydischarge efficiency. Moreover, the input voltage and currentregulations provide maximum charging power delivery to thebattery with various types of input sources.
A wide range of input sources are supported, includingstandard USB hosts, charging ports and USB compliant highvoltage adaptors. The default input current limit isautomatically selected based on the built-in USB interface.This limit is determined by the detection circuit in the system(e.g. USB PHY). The SGM41519 is USB 2.0 and USB 3.0power specifications compliant with input current and voltageregulation.
The SGM41519 is capable of boosting the battery voltage tosupply 5.15V (adjustable 4.85V/5V/5.15V/5.3V) on PMID.The Boost mode is used to charge another battery by thecontrol of PMID_GD. The PMID_GD pin is used to drive anexternal P-MOSFET to disconnect Boost output PMID fromattached accessories.
The system voltage is regulated slightly above the batteryvoltage by the power path management circuit and is keptabove the programmable minimum system voltage (3.5V bydefault). Therefore, system power is maintained even if the battery is completely depleted or removed. Dynamic powermanagement (DPM) feature is also included thatautomatically reduces the charge current if the input currentor voltage limit is reached. If the system load continues toincrease after reduction of charge current down to zero, thepower path management provides the deficit from battery bydischarging battery to the system until the system powerdemand is fulfilled. This is called supplement mode, whichprevents the input source from overloading.
Starting and termination of a charging cycle can beaccomplished without software control. The sensed batteryvoltage is used to decide for starting phase of charging in oneof the three phases of charging cycle: pre-conditioning,constant current or constant voltage. When the chargecurrent falls below a preset limit and the battery voltage isabove recharge threshold, the charger function willautomatically terminate and end the charging cycle. If thevoltage of a charged battery falls below the rechargethreshold, the charger begins another charging cycle.
Several safety features are provided in the SGM41519 suchas over-voltage and over-current protections, batterytemperature monitoring, charging safety timing, thermalshutdown and input UVLO. TS pin is connected to an NTCthermistor for battery temperature monitoring and protectionin both charge and Boost modes according to JEITA profile.This device also features thermal regulation in which thecharge current is reduced, if the junction temperatureexceeds 80℃ or 120℃ (selectable).
Charging status is reported by the STAT output andfault/status bits. A negative pulse is sent to the nINT outputpin as soon as a fault occurs to notify the host. BATFET resetcontrol is provided by nQON pin to exit ship mode or for a fullsystem reset.The SGM41519 is available in a Green TQFN-4×4-24Lpackage.
