2-PHASE STEPPER MOTOR DRIVER

A: Recommended operational range

B: External Schottky diode to be connected between output

terminal and power terminal as well as between output terminal

and GND.

V This regulation is for temporary electric power use. For

continuous use, be sure power dissipation does not go beyond

package’s operational range.

θj-c = 8°C/W

A: Mounted on 25cm2 glassfiber epoxy resin circuit board with one

side copper-foiled

θc-a = 42°C/W

B: With aluminum heat sink (1t) 10cm2

θc-a = 25°C/W

C: With aluminum heat sink (1t) 100cm2

θc-a = 10°C/W

Tj(max) = 150°C
