Note 1: Perform thermal calculations for the maximum current value under normal conditions. Use the IC at 1.5 A or less per phase.The current value maybe controled according to the ambient temperature or board conditions.
Note 2: Input 7 V or less as VIN
Note 3: Measured for the IC only. (Ta = 25)
Note 4: Measured when mounted on the board. (Ta = 25)
Ta: IC ambient temperature Topr: IC ambient temperature when starting operation
Tj: IC chip temperature during operation Tj (max) is controlled by TSD (thermal shut down circuit)
The TB62206FG is designed to drive a 2−phase bipolar setpping motor. With BiCD process technology, this device enables output withstand voltage of 40 V and maximum current of 1.8 A to be achieved.
