MOS INTEGRATED CIRCUIT
µPD16818
MONOLITHIC DUAL H BRIDGE DRIVER CIRCUIT
DESCRIPTION
The
µPD16818 is a monolithic dual H bridge driver IC which uses N-channel power MOS FETs in its output stage. By
employing the power MOS FETs for the output stage, this driver circuit has a substantially improved saturation voltage and
power consumption as compared with conventional driver circuits that use bipolar transistors.
In addition, the drive current can be adjusted by an external resistor in power-saving mode.
The
µPD16818 is therefore ideal as the driver circuit of a 2-phase excitation, bipolar-driven stepping motor for the head
actuator of an FDD.
FEATURES
Compatible with 3V-/5V- supply voltage
Pin compatible with
µPD16803
Low ON resistance (sum of ON resistors of top and bottom MOS FETs)
RON1= 1.2
Ω (VM = 3.0 V)
