Turn Off Delay Time

It is the time from when Vgs drops below 90% of the gate drive voltage to when the drain current drops below 90% of the load current. It is the delay before current starts to transition in the load, and depends on Rg. Ciss.

300 ns

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.

-40°C~150°C TJ

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.

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.

300mA

Output Configuration

Positive, Isolation Capable

Output Current

The rated output current is the maximum load current that a power supply can provide at a specified ambient temperature. A power supply can never provide more current that it's rated output current unless there is a fault, such as short circuit at the load.

Max Output Voltage

The maximum output voltage refers to the dynamic area beyond which the output is saturated in the positive or negative direction, and is limited according to the load resistance value.

Rise Time

In electronics, when describing a voltage or current step function, rise time is the time taken by a signal to change from a specified low value to a specified high value.

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).

Nominal Input Voltage

The actual voltage at which a circuit operates can vary from the nominal voltage within a range that permits satisfactory operation of equipment. The word “nominal” means “named”.

Power Consumption

Power consumption is the amount of input energy (measured in watts) required for an electrical appliance to function. This is opposed to power output which is a measure of the level of performance, of a heat pump for example.

Clock Sync

Clock synchronization is a topic in computer science and engineering that aims to coordinate otherwise independent clocks. Even when initially set accurately, real clocks will differ after some amount of time due to clock drift, caused by clocks counting time at slightly different rates.
