MONOLITHIC QUAD H-BRIDGE DRIVER CIRCUIT
DESCRIPTION
The µPD168101 is monolithic quad H-bridge driver LSI which uses power MOSFETs in the output stages. By
using the MOS process, this driver IC has substantially improved the voltage loss of the output stage and power
consumption as compared with conventional driver circuits using bipolar transistors.
By eliminating the charge pump circuit, the current during power-OFF is drastically decreased.
In addition, a low-voltage malfunction prevention circuit is also provided that prevents the IC from malfunctioning
when the supply voltage drops.
As the package, a 24-pin plastic TSSOP is adopted to enable the creation of compact, slim application sets.
This driver IC can drive two stepping motor at the same time, and is ideal for driving stepping motors in the lens of
a camera. It is the best for lens drive drivers, such as a digital camera and a video camera. Moreover, since the
input of two terminals is respectively owned to H bridge 1 circuit, a maximum of four loads, such as DC motor, can be
driven simultaneously.
