F, 22-Oct-07 www.vishay.com 1 Buffered H-Bridge FEATURES • 1.0 A H-Bridge • 200 kHz Switching Rate • Shoot-Through Limited • TTL Compatible Inputs • 3.8 to 13.2 V Operating Range • Surface Mount Packaging APPLICATIONS • VCM Driver • Brushed Motor Driver • Stepper Motor Driver • Power Converter • Optical Disk Drives • Power Supplies • High Performance Servo DESCRIPTION The Si9986 is an integrated, buffered H-bridge with TTL compatible inputs and the capability of delivering a continuous 1.0 A at VDD = 12 V (room temperature) at switching rates up to 200 kHz. Internal logic prevents the upper and lower outputs of either half-bridge from being turned on simultaneously. Unique input codes allow both outputs to be forced low (for braking) or forced to a high impedance level. The Si9986 is available in both standard and lead (Pb)-free, 8-pin SOIC packages, specified to operate over a voltage range of 3.8 V to 13.2 V, and the commercial temperature range of 0 to 70 °C (C suffix) and the industrial temperature range of - 40 to 85 °C (D suffix).
