MOS INTEGRATED CIRCUIT
µ PD168002
MONOLITHIC 6-CHANNEL H-BRIDGE DRIVER
DESCRIPTION
The µ PD168002 is a monolithic 6-channel H-bridge driver that consists of a CMOS control circuit and a MOS output
stage. It can reduce the current consumption and the voltage loss at the output stage compared with conventional
driver using bipolar transistors, thanks to employment of a MOS process. The µ PD168002 employs P-channel MOS
FET in the output stage, and is eliminated the charge pump circuit. Therefore, the circuit current consumption during
operation can be significantly reduced.
The package is a 48-pin TQFP that helps reduce the mounting area and height.
The µ PD168002 can be used to drive one stepping motor and four DC motors, and is suitable for the motor driver of
CD-ROM/CD audios.
FEATURES
• Six H-bridge circuits employing power MOS FET
• Low current consumption due to elimination of charge pump circuit
• Input logic frequency: 100 kHz supported
• 3 V power supply supported for logic
Minimum operating supply voltage: 2.7 V
• 5 V, 10 V power supply supported for motor
ch1, ch2, ch5 and ch6: 10 V driving
ch3 and ch4: 5 V driving
• Undervoltage lockout circuit
Shuts down the internal circuit at VDD = 1.7 V TYP.
• Overheat protection circuit
• 48-pin TQFP (□7 mm)

Note The conditions of VINB = H is valid only at ch1, ch2 and ch6. The through current may be flowed, if the switching
operation is performed under the conditions of VINB = H at ch3 to ch5.
Remark The high impedance period of about 50 ns is prepared for the through-current prevention at the time of mode
switching. The tr (rise time) is designed as 50 ns, and the tf (fall time) is designed as about 50 ns.
