SI9987CY-E3

Overview

The SI9987CY-E3 is a buffered H-Bridge motor driver manufactured by Vishay / Siliconix. It operates within a supply voltage range of 3.8V to 13.2V and draws a typical quiescent current of 2.5 mA. The component is housed in an SOIC-8 surface-mount package and supports installation via SMD/SMT techniques. It functions as a half-bridge driver suitable for motor control applications, with a specified operating temperature range from 0°C to +70°C.

Feature Summary

• Integrated buffered H-Bridge architecture for motor drive applications
• Low power consumption with minimal quiescent current draw
• Compatible with standard surface-mount assembly processes

Applications

• Motor control systems
• Motion control circuits
• Ignition controllers

Procurement Notes

This component is officially designated as End-of-Life (EOL) by the manufacturer. Availability is restricted, and distributors may not stock this item in all regions. Verification of current lifecycle status and alternative sourcing options is required before integration into new designs.

Selection Notes

Engineers should evaluate the limited operating temperature range of 0°C to +70°C against environmental requirements. The SOIC-8 package constrains thermal dissipation capabilities compared to larger footprints. Consideration of the EOL status is critical for long-term production viability.

Part Context

The SI9987CY-E3 belongs to the Vishay Siliconix portfolio of motor and motion controllers. It serves as a specialized integrated circuit designed to drive loads requiring bipolar or H-Bridge configurations. The part is categorized under PMIC and Motor Drivers within the manufacturer's classification system.

Replacement Considerations

Public documentation identifies the SI9986CY-E3 as a recommended alternative. Both components share similar half-bridge characteristics and packaging, though specific electrical parameters should be verified for compatibility.
