Bh3950ku E2
Overview
Product sourcing insights & recommendations
The BH3950KU-E2 is a specialized Power Management Integrated Circuit (PMIC) manufactured by ROHM Semiconductor, primarily used as a motor driver for DVD and CD drives.
Product Overview
* Primary Function: It is a Dual H-Bridge Motor Driver designed to control two DC motors simultaneously with forward/reverse and constant speed synchronization Allicdata.
* Technical Specs: It supports up to 500mA per phase load and utilizes Pulse Width Modulation (PWM) for precise speed, torque, and positional control Allicdata.
* Key Features: Includes active braking, automatic current limiting, dead time control, and built-in protection against low voltage Allicdata.
Market Trends & Insights
* Lifecycle Status: The product is officially Obsolete (EOL). ROHM issued an obsolescence notice on March 1, 2022, and it is no longer recommended for new designs Digikey.
* Supply Dynamics: While large distributors like DigiKey and Mouser list it as obsolete, secondary B2B platforms and surplus electronics suppliers still show fragmented "Original New" stock CenstryIc365Buy. Prices on the secondary market range from approximately $2.50 to $8.00 per unit depending on quantity AllicdataSicstock.
* Application Shift: Originally built for the optical drive market, the trend for such motor drivers has shifted towards Robotics, 3D printing, and Smart Home automation (e.g., electronic door openers), where legacy stock is often repurposed due to its stable H-bridge performance Allicdata.
For professional sourcing, verified suppliers like MEGA SOURCE ELEC. LIMITED and Shenzhen Working Technology specialize in sourcing such integrated circuits and ROHM-branded components for maintenance and legacy support AlibabaAlibaba.
