DATA SHEET
MOS INTEGRATED CIRCUIT
µ PD168113
SERIAL CONTROL 7-CHANNEL H-BRIDGE DRIVER
DESCRIPTION
The µ PD168113 is a serial control 7-channel H-bridge driver that consists of a CMOS controller and a MOS output
stage. It can reduce the current consumption and the voltage loss at the output stage compared with a conventional
driver using bipolar transistors, thanks to employment of a MOS process. The µ PD168113 can drive various motor
coils by controlling the serial, so that the number of signal lines necessary for controlling the motor can be decreased.
The package is a 56-pin WQFN that helps reduce the mounting area and height.
The µ PD168113 can be used to drive two stepping motors, or two DC motors and one coil.
FEATURES
• Seven H-bridge circuits employing power MOS FET
• Low-voltage driving
VDD = 2.7 to 3.6 V
VM = 2.7 to 5.5 V
• Output on-state resistance: 1.0 Ω TYP., 1.5 Ω MAX. (sum of top and bottom stage)
• Output current
<1 ch to 6 ch>
DC current: 0.4 A/ch (when each channel is used independently)
Peak current: 0.7 A/ch (when each channel is used independently)
<7 ch>
DC current: 0.5 A/ch (when used independently)
Peak current: 0.7 A/ch (when used independently)
• Input logic frequency: 6 MHz supported
• Undervoltage lockout circuit
Shuts down the internal circuit at VDD = 1.7 V TYP.
• Overheat protection circuit
Operates at 150°C or more and shuts down internal circuitry.
• 56-pin WQFN (□8 mm, 0.5 mm pitch)

Cautions 1. Be sure to connect all of the pins which have more than one.
2. A pull-down resistor (50 to 200 kΩ) is connected to the TEST, IN5A, IN5B, IN6A, IN6B, IN7A and IN7B
pins.
Fix these input pins to GND when they are not used.

8. NOTES ON TRANSMITTING DATA
• The first input data is loaded when SCLK changes from L to H after LATCH has changed from L to H.
Data is transmitted in 16-bit units, and is determined when LATCH changes from H to L. Invalid data of less than
16-bit is discarded.
• Data of different addresses can be input successively while LATCH = H.
• The access time can be shortened by updating only the necessary data after initialization has been performed.
If an address is not input, the previous value of that address is held as the data.
Examples) DC motor and constant current: The ON/OFF state is held.
Stepping motor: The excitation position is held if the excitation state is in ON.
• If the same address is input more than one while LATCH = H, the last input data is valid.
• If invalid data and correct data are input while LATCH = H, only the correct data is valid.
• If only LATCH is input, the data is not updated, and the driver holds the current status.
• If a command related to stepping motors (addresses 8 to F) is input during the “wait period” that lasts from input of
the preceding data to the start of counting, the data is ignored. A command related to the DC motor and coil
(addresses 3 to 7) is valid during the synchronization period.
• Data that is input when RESETB = L is ignored.
