描述 Description

DESCRIPTION
The µPD168110 is a monolithic 2-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 employmentof a MOS process. This product employs a P-channel MOSFET on the high side ofthe output stage, eliminating a charge pump. As a result, the circuit current consumption can be substantially reduced during operation.FEATURES
O Two H bridge circuits employing power MOSFET
O Current feedback 64-step microstep driving and two-phase excitation driving selectable
O Low on-resistance: 2 ΩMAX.
O 3 V power supply
   Minimum operating power supply voltage VDD= 2.7 V
O Under voltage lockout circuit
   Shuts down internal circuitry at VDD= 1.7 V TYP.
O 24-pin TSSOP
