MOS INTEGRATED CIRCUIT
µ PD168116A
7-CHANNEL H-BRIDGE DRIVER
WITH A MICRO STEP FUNCTION SUPPORTING PULSE INPUT
DESCRIPTION
The µ PD168116A is a 7-channel H-bridge driver with a micro step function supporting pulse input 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 a conventional driver using bipolar transistors, thanks to employment of a MOS process.
The µ PD168116A can drive a stepping motor by inputting pulses, 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 PD168116A can be used to drive two stepping motors, or two DC motors and one coil.
FEATURES
• Seven H-bridge circuits employing power MOSFET
• 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, ch1 to ch4, and ch7)
1.5 Ω TYP., 2.0 Ω MAX. (sum of top and bottom stage, ch5 and ch6)
• PWM output (ch1 to ch6) , linear output (ch7)
• Output current
<ch1 to ch6>
DC current: 0.4 A/ch (when each channel is used independently)
Peak current: 0.7 A/ch (when each channel is used independently)
<ch7>
DC current: 0.5 A/ch (when used independently)
Peak current: 0.7 A/ch (when used independently)
• Input logic frequency: 100 kHz 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)
