  Vishay Siliconix Si9986 1 Buffered H-Bridge FEATURES  1.0 A H-Bridge ã200 kHz Switching Rate ãShoot-Through Limited ãTTL Compatible Inputs ã3.8 to 13.2 V Operating Range ãSurface Mount Packaging APPLICATIONS  ãVCM Driver ãBrushed Motor Driver ãStepper Motor Driver ãPower Converter ãOptical Disk Drives ãPower Supplies ãHigh Performance Servo DESCRIPTION The Si9986 is an integrated, buffered H-bridge with TTLcompatible inputs and the capability of delivering acontinuous 1.0 A at V DD  = 12 V (room temperature) atswitching rates up to 200 kHz. Internal logic prevents theupper and lower outputs of either half-bridge from beingturned on simultaneously. Unique input codes allow bothoutputs to be forced low (for braking) or forced to a highimpedance level.The Si9986 is available in both standard and lead (Pb)-free,8-pin SOIC packages, specified to operate over a voltagerange of 3.8 V to 13.2 V, and the commercial temperaturerange of 0 to 70 °C (C suffix) and the industrial temperaturerange of - 40 to 85 °C (D suffix).

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Notes: a. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.b. Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing.
