| Si9987 New Product Vishay Siliconix Si9987 Buffered H-Bridge FEATURES * * * * * * 1.0-A H-Bridge 500-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 Si9987 is an integrated, buffered H-bridge with TTL compatible inputs and the capability of delivering a continuous 1.0 A @ VDD = 5.0 V (room temperature) at switching rates up to 500 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 Si9987 is available in an 8-Pin SOIC package, specified to operate over a voltage range of 3.8 V to 13.2 V, and the commercial temperature range of 0 to 70C (C suffix) and -40 to 85C (D suffix).
