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.

Controller - Commutation, Direction Management

Number of Outputs

2

Output Voltage

3.9V

Operating Supply Voltage

The voltage level by which an electrical system is designated and to which certain operating characteristics of the system are related.

5V

Supply Voltage-Max (Vsup)

7V

Power Supplies

an electronic circuit that converts the voltage of an alternating current (AC) into a direct current (DC) voltage.?

5V

Interface

Parallel

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.

80mA

Output Configuration

Pre-Driver - Half Bridge (4)

Power Dissipation

the process by which an electronic or electrical device produces heat (energy loss or waste) as an undesirable derivative of its primary action.

1W

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.

10mA

Collector Emitter Voltage (VCEO)

10V

Motor Type

Stepper

Motor Type - Stepper

Bipolar, Unipolar

Step Resolution

Servo motor resolution is determined by feedback device of motor. I.e. 1000 PPR (pulses per revolution) quadrature encoder yields 1/4000 revolution resolution because 1000 PPR equals 4000 counts per revolution after standard 4X decoding.

Radiation Hardening

Radiation hardening is the process of making electronic components and circuits resistant to damage or malfunction caused by high levels of ionizing radiation, especially for environments in outer space (especially beyond the low Earth orbit), around nuclear reactors and particle accelerators, or during nuclear accidents or nuclear warfare.
