Overview
The SI9986CY-T1-E3 is a buffered H-bridge motor driver manufactured by Vishay Siliconix, designed for brushed and stepper motor applications. It operates within a supply voltage range of 3.8 V to 13.2 V and supports switching rates up to 200 kHz. The device delivers a continuous output current of 1.0 A at VDD = 12 V under room temperature conditions. It features TTL-compatible inputs and includes internal logic to prevent shoot-through currents. The component is housed in an 8-pin SOIC surface-mount package and is specified for the commercial temperature range of 0°C to +70°C.
Feature Summary
- Integrated shoot-through prevention logic prevents simultaneous activation of upper and lower half-bridge outputs.
- Supports unique input codes to force both outputs low for braking or high impedance states.
- TTL-compatible input interface simplifies control logic integration.
Applications
- Brushed DC Motor Driver
- Stepper Motor Driver
- Optical Disk Drives
Procurement Notes
This component is officially designated as End-of-Life (EOL) by Vishay Siliconix. Distribution channels indicate that Mouser does not currently stock this item in all regions. Buyers must verify final availability through authorized distributors and confirm compliance with RoHS directives via official documentation before procurement.
Selection Notes
Select this part for designs requiring a buffered H-bridge with integrated protection against cross-conduction. It is suitable for low-voltage systems operating between 3.8 V and 13.2 V. Ensure the application requires the commercial temperature rating of 0°C to +70°C, as industrial variants use different suffixes.
Part Context
The SI9986 belongs to the Vishay Siliconix family of power management ICs and motor controllers. It is specifically categorized under Motor / Motion / Ignition Controllers & Drivers. The 'C' suffix denotes the commercial temperature range, while 'E3' indicates lead-free packaging compliant with environmental standards.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. As the component is End-of-Life, alternative solutions require manual evaluation based on functional requirements such as H-bridge configuration and current ratings.
