DESCRIPTION
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.
actuator of an FDD.
FEATURES
• Low ON resistance (sum of ON resistors of top and bottom transistors)
• Low current consumption: I
• Stop mode function that turns OFF all output transistors
• Compact surface mount package: 20-pin plastic SOP (300 mil)
PIN CONFIGURATION (Top View)
The PD16803 is a monolithic dual H bridge driver circuit which uses N-channel power MOS FETs in its driver stage.
In addition, the drive current can be adjusted by an external resistor in a power-saving mode.
The PD16803 is therefore ideal as the driver circuit of the 2-phase excitation, bipolar-driven stepping motor for the head
