STK681-050

The STK681-050 is a bidirectional DC brush-type motor driver IC with brake function that incorporates MOSFET power elements.The STK681-050 is designed for (1)PPC drum and scanner motor drivers; (2)LPP drum motor drivers; (3)printer head and carriage motor drivers; (4)general DC motor applications.No products described or contained herein are intended for use in surgical implants, life-support systems, aerospace equipment, nuclear power control systems,vehicles, disaster/crime-prevention equipment and the like, the failure of which may directly or indirectly cause injury,death or property loss.

Features of the STK681-050 are:(1)h-bridge output stage configuration employing 4 MOS-FETs; (2)independent TTLICMOS-level control for each MOS-FET (4-pin control); (3)external signal control of forward, reverse and brake operation; (4)MOSFETs supporting 12A peak starting current and 13.5A peak brake current (F3 and F4 ON); (5)DC input supporting saturation operation; (6)only 1 charge pump electrolytic capacitor required,compared with the STK6875 which requires 2.

The absolute maximum ratings of the STK681-050 can be summarized as:(1)operating substrate temperature:105;(2)storage temperature:-40 to 125;(3)maximum supply voltage 1:50V;(4)junction temperature:150;(5)maximum input voltage:±10V;(6)maximum supply voltage 2:10V.The information given herein, including the specifications and dimensions, is subject to change without prior notice to improve product characteristics.
