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.

MAX8903DETI+ General Description

The MAX8903A–MAX8903E/MAX8903G/MAX8903H/MAX8903J/MAX8903N/MAX8903Y are integrated 1-cellLi+ chargers and Smart Power Selectors™ with dual(AC adapter and USB) power inputs. The switch modecharger uses a high switching frequency to eliminateheat and allow tiny external components. It can operatewith either separate inputs for USB and AC adapterpower, or from a single input that accepts both. Allpower switches for charging and switching the loadbetween battery and external power are included on-chip. No external MOSFETs, blocking diodes, or cur-rent-sense resistors are required.The MAX8903_ features optimized smart power controlto make the best use of limited USB or adapter power.Battery charge current and SYS output current limit areindependently set. Power not used by the systemcharges the battery. Charge current and SYS output cur-rent limit can be set up to 2A while USB input current canbe set to 100mA or 500mA. Automatic input selectionswitches the system from battery to external power. TheDC input operates from 4.15V to 16V with up to 20V pro-tection, while the USB input has a range of 4.1V to 6.3Vwith up to 8V protection.The MAX8903_ internally blocks current from the bat-tery and system back to the DC and USB inputs whenno input supply is present. Other features include pre-qual charging and timer, fast charge timer, overvoltageprotection, charge status and fault outputs, power-OKmonitors, and a battery thermistor monitor. In addition,on-chip thermal limiting reduces battery charge rateand AC adapter current to prevent charger overheat-ing. The MAX8903_ is available in a 4mm x 4mm, 28-pinthin QFN package.The various versions of the MAX8903_ allow for designflexibility to choose key parameters such as systemregulation voltage, battery prequalification threshold,and battery regulation voltage. The MAX8903B/MAX8903E/MAX8903G also includes power-enable onbattery detection. See the Selector Guide section forcomplete details.
