3 / 14 page © 1997 DATA SHEET MOS INTEGRATED CIRCUIT µPD16814 MONOLITHIC DUAL H BRIDGE DRIVER CIRCUIT DESCRIPTION The µPD16814GS is a monolithic dual H bridge driver circuit employing a power MOS FET for its driver stage. By complementing the P channel and N channel of the output stage, the circuit current is substantially improved as compared with that of the conventional charge pump driver. Because the dual H bridge driver circuits at the output stage are independent of each other, this IC is ideal as the driver circuit for a 1- to 2-phase excitation bipolar driving stepping motor for the head actuator of an FDD. FEATURES • Low ON resistance (sum of ON resistance of top and bottom FETs) RON1 = 2.0 Ω TYP. • Low current consumption: IDD = 100 µA MAX. • Four input modes independently controlling dual H bridge drivers • Stop and Brake modes selectable • Surface-mount mini-mold package: 16-pin plastic SOP (300 mil) PIN CONFIGURATION (Top View) VM1 1A PGND1 2A VDD IN1 IN3 IN2 NC 1B PGND2 2B VM2 SEL IN4 DGND 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 ORDERING INFORMATION Part Number Package µPD16814GS 16-pin plastic SOP (300 mil) The information in this document is subject to change without notice.
