BD65492MUV
General Description
The BD65492MUV provides a dual H-bridge motor
driver which features wide range of motor power supply
voltage from 1.8V to 16.0V and low power consumption
to switch low ON-Resistance DMOS transistors at high
speed. This small surface mounting package is most
suitable for mobile system, home appliance and various
applications.

It's better for VM pin groups of 9,10 and 21,22 to short-circuit on the
PCB pattern. If cannot, check into transitional characteristics of total
application circuit including two motors. Through low impedance
materials, the possibility of causing some unexpected malfunctions
is incontrovertible.
