Hardware setting of the STEVAL-IHM023V2

Doc ID 15870 Rev 4

Table 3 shows jumper settings for a low-voltage BLDC motor. Please confirm that the input

voltage (mains voltage) of the demonstration board in this case is in the range of 18 VDC to

35 VDC. If it is necessary to supply the motor with a voltage lower than 18 VDC, please

remove the W3 jumper and connect the auxiliary voltage to the J3 connector. This

configuration is called “dual supply configuration”.

In this configuration it may be necessary to modify R2, R4, and R7 resistors according to

applied supply voltage.

W13

Single-shunt

W14

Present for voltage doubler

Not present for standard voltage range

W16

Dash mark position of Hall/encoder with VDD

Not marked position for supplying Hall/encoder with +5 V

“3.3 V” position for VDD = 3.3 V

“5 V” position for VDD = 5 V

“<35 V ONLY” position

Present for Hall sensor or encoder

Not present for connected tachometer
