Figure 7: two unidirectional DC motors - higher current
2.2.5
Mode no. 5: parallel connection for lower overcurrent - one DC motor
bidirectional
This mode, with output power in parallel, maintains a lower operating current compared to
the solution in mode 3, but power dissipation is reduced.
The motor supply voltage is connected to J1 pin 5 and 6 with a maximum voltage of 50 V
DC.
Maximum current is 2.8 A RMS and the output R
DS(on)
is equal to 0.15 W (Th = 25 °C).
The maximum overcurrent detection threshold is set to 5.6 A.
Motor A connected between
Both A+ (CN1 pin1) A- (CN1 pin2)
Both B+ (CN1 pin4) B- (CN1 pin3)
