QUICK REFERENCE

462

IB He

ULTRAMINIATURE BIPOLAR
STEPPING MOTOR DRIVER
The IB462He, INT-462 and OSC-
426H are sensitive to Electrostatic
Discharge (ESD).
Hazardous Voltage Levels may
be present if using an open
frame power supply to power the
IB462He, INT-462 or OSC-462H.
The Power Supply output voltage
must not exceed the maximum
input voltage of the IB462He,INT-
462 or OSC-462H.
Do not apply power to the IB462He
without proper heat sinking or
cooling. The max. rear plate
temperature is 70°C!
The rear mounting surface of the
driver contains various voltages and
must be kept isolated when attached
to a conductive surface!
Do not "Hot Plug" Power or Motor
Connection while power is applied
to any of the IB462He drivers or
accesories.

IB462He Mounting Requirements
The IB462H is designed to be socketed or soldered into a PCB. For PCB layout information and circuit board hole pattern please refer to the IB462He Manual, Section 1.7. This part of the Quick Reference only supplies Mechanical Mounting information.Heat sinking and the use of the included insulating thermal pad are ABSOLUTELY REQUIRED for the IB462He driver at all power levels. Below are some examples of mounting configurations.
