What is the Surface Mount ?

having leads that are designed to be soldered on the side of a circuit board that the body of the component is mounted on.

What is the Operating Temperature ?

The operating temperature is the range of ambient temperature within which a power supply, or any other electrical equipment, operate in. This ranges from a minimum operating temperature, to a peak or maximum operating temperature, outside which, the power supply may fail.

What is the Packaging ?

Semiconductor package is a carrier / shell used to contain and cover one or more semiconductor components or integrated circuits. The material of the shell can be metal, plastic, glass or ceramic.

What is the Part Status ?

Parts can have many statuses as they progress through the configuration, analysis, review, and approval stages.

What is the Terminal Form ?

Occurring at or forming the end of a series, succession, or the like; closing; concluding.

What is the Terminal Pitch ?

The center distance from one pole to the next.

What is the Max Supply Voltage ?

In general, the absolute maximum common-mode voltage is VEE-0.3V and VCC+0.3V, but for products without a protection element at the VCC side, voltages up to the absolute maximum rated supply voltage (i.e. VEE+36V) can be supplied, regardless of supply voltage.

What is the Min Supply Voltage ?

The minimum supply voltage (V min ) is explored for sequential logic circuits by statistically simulating the impact of within-die process variations and gate-dielectric soft breakdown on data retention and hold time.

What is the Nominal Supply Current ?

Nominal current is the same as the rated current. It is the current drawn by the motor while delivering rated mechanical output at its shaft.

What is the Quiescent Current ?

The quiescent current is defined as the current level in the amplifier when it is producing an output of zero.

What is the Synchronous Rectifier ?

Synchronous rectification is a technique for improving the efficiency of rectification by replacing diodes with actively controlled switches, usually power MOSFETs or power bipolar junction transistors (BJT).

What is the RoHS Status ?

RoHS means “Restriction of Certain Hazardous Substances” in the “Hazardous Substances Directive” in electrical and electronic equipment.

The bq24190, bq24192, and bq24192I are highly-integrated switch-mode battery charge management and system power path management devices for single cell Li-Ion and Li-polymer battery in a wide range of tablet and other portable devices.

Its low impedance power path optimizes switch-mode operation efficiency, reduces battery charging time and extends battery life during discharging phase. The I2C serial interface with charging and system settings makes the device a truly flexible solution.

The device supports a wide range of input sources, including standard USB host port, USB charging port and high power DC adapter. To set the default input current limit, the bq24190 detects the input source following the USB battery charging spec 1.2, and the bq24192 and bq24192I take the results from detection circuit in the system, such as USB PHY device. The bq24190,192, and 192I are compliant with USB 2.0 and USB 3.0 power specifications with input current and voltage regulation. Meanwhile, the bq24190, bq24192, and bq24192I meet USB On-the-Go operation power rating specification by supplying 5 V on the VBUS with a current limit up to 1.3 A.

The power path management regulates the system slightly above battery voltage but does not drop below 3.5-V minimum system voltage (programmable). With this feature, the system maintains operation even when the battery is completely depleted or removed. When the input current limit or voltage limit is reached, the power path management automatically reduces the charge current to zero. As the system load continues to increase, the power path discharges the battery until the system power requirement is met. This supplement mode operation prevents overloading the input source.

The devices initiate and complete a charging cycle without software control. It automatically detects the battery voltage and charges the battery in three phases: pre-conditioning, constant current and constant voltage. At the end of the charging cycle, the charger automatically terminates when the charge current is below a preset limit in the constant voltage phase. When the full battery falls below the recharge threshold, the charger will automatically start another charging cycle.

The bq24190, bq24192, and bq24192I provide various safety features for battery charging and system operation, including dual pack negative thermistor monitoring, charging safety timer and over-voltage/over-current protections. The thermal regulation reduces charge current when the junction temperature exceeds 120°C (programmable).

The STAT output reports the charging status and any fault conditions. The PG output in the bq24192 and bq24192I indicates if a good power source is present. The INT immediately notifies the host when a fault occurs.

The bq24190, bq24192, and bq24192I areavailable in a 24-pin, 4.00 × 4.00 mm2 thin VQFN package.
