Description of Blocks

1. Motor Control Input

(a) ENABLE12, ENABLE34, INPUT1 to INPUT6 Pins

Logic level controls the output logic of H-Bridge.

(See the Electrical Characteristics; p.4/12, and I/O Truth Table; p.5/12)

(b) BRAKE5 & BRAKE6 Pins

Logic high puts the device in short brake mode.

(See the Electrical Characteristics; p.4/12 and I/O Truth Table; p.5/12)

2. H-Bridge

Each H-bridge can be controlled independently. It is therefore possible to drive the H-bridges simultaneously, as long

as the package thermal tolerances are not exceeded. Because the respective output transistors consist of power

CMOS which consumes a motor power supply VM, the ON-Resistance value of high and low-side total is dependent

on VM voltage. Further, the whole application must be designed so that the maximum current of each channel may

be 500mA or below. (See the Recommended Operating Conditions; p.4/12)
