DESCRIPTION

The

µPD168302 is monolithic dual H-bridge driver LSI which uses power MOS FETs in the output stages. By using

the MOS process, this driver has substantially improved the voltage loss of the output stage and power consumption

as compared with conventional driver using bipolar transistors.

As the package, a 24-pin plastic TSSOP is adopted to enable the creation of compact, slim application sets.

It is provided with forward/reverse and brake functions and is ideal as a driver for DC motor and stepping motor.

FEATURES

• 2ch H-Bridge circuit employing power MOS FETs

• Charge-pump circuit for low-voltage operation

• Low output FET on resistance: 1.0 Ω TYP. 2.0 Ω MAX. (Sum of upper and lower side)

• Output current: DC current 0.6 A/ch

Peak current 1.0 A/ch

• Input logic frequency: 100 kHz

• 5 V logic power supply: Minimum operating supply voltage 4.0 V

• 0.9 to 3.6 V power supply for motor drive

• 24-pin plastic TSSOP (5.72 mm (225), 0.5 mm pitch)
