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 bq25122 is a highly integrated battery charge management IC that integrates the mostcommon functions for wearable devices: Linear charger, regulated output, load switch, manual resetwith timer, and battery voltage monitor. The integrated buck converter is a high efficiency, lowIQ switcher using DCS control that extends light load efficiency down to10-μA load currents. The low quiescent current during operation and shutdown enables maximumbattery life. The device supports charge currents from 5 mA to 300 mA. The input current limit,charge current, buck converter output voltage, LDO output voltage, and other parameters areprogrammable through the I2C interface.

The battery is charged using a standard Li-Ion charge profile with three phases:precharge, constant current and constant voltage. A voltage-based JEITA compatible battery packthermistor monitoring input (TS) is included that monitors battery temperature and automaticallychanges charge parameters to prevent the battery from charging outside of its safe temperaturerange. The charger is optimized for 5-V USB input, with 20-V tolerance to withstand linetransients. The buck converter is run from the input or battery. When in battery only mode, thedevice can run from a battery up to 4.65 V.

A configurable load switch allows system optimization by disconnecting infrequently useddevices. The manual reset with timer allows multiple different configuration options for wake arereset optimization.
