µPD16813
MONOLITHIC DUAL H BRIDGE DRIVER CIRCUIT
DESCRIPTION
The µPD16813 is a monolithic dual H bridge driver circuit which uses power MOS FETs in its driver stage. By
complementing the P channel and N channel of the output stage, the circuit current has been substantially inproved
as compared with that of conventional charge pump drivers.
The µPD16813 is therefore ideal as the driver circuit of the 2-phase excitation, bipolar-driven stepping motor for
the head actuator of an FDD.
FEATURES
• Low ON resistance (sum of ON resistors of top and bottom transistors)
RON = 2.0 Ω TYP.
• Low current consumption: IDD = 100 µA MAX.
• Noise reduction circuit that operates when INC is OFF.
• Compact surface mount package: 16-pin plastic SOP (300 mil)
