Overview
The BH5510KV-E2 is a system motor driver IC designed for slim drive applications, manufactured by ROHM Semiconductor. It operates within a supply voltage range of 4 V to 5.5 V and delivers an output current of 3 A. The device features six outputs and functions at a working frequency of 300 kHz with a power dissipation of 1.37 W. It supports an operating temperature range from -40 °C to +85 °C and is housed in a VQFP-48 package.
Feature Summary
- Utilizes ROHM's proprietary S!PWM×2 ultra-silent driving method for the spindle motor driver to achieve low noise operation.
- Integrates gain switching functionality within the spindle motor driver to ensure stable circuit performance at low speeds.
- Features a linear transmission coil driver without dead zones or induction bands, allowing optimization of frequency characteristics via external R.C components.
Applications
- Spindle motor drivers in optical disc drives
- Transmission coil drivers in optical disc mechanisms
- Eject motor drivers when tilt coil loads are absent
Procurement Notes
Verify component authenticity through authorized channels as this part may be subject to end-of-life restrictions. Confirm RoHS compliance status and specific ordering suffixes against official datasheets before procurement. Ensure storage conditions meet humidity sensitivity requirements to prevent damage prior to assembly.
Selection Notes
Select this component for applications requiring integrated control of spindle and transmission motors in slim form factors. Evaluate thermal management capabilities given the 1.37 W power dissipation rating. Ensure the design accommodates the VQFP-48 package dimensions and pin configuration for proper PCB layout integration.
Part Context
This component belongs to the BH5510KVT series of system motor drivers. It is specifically engineered for optical disk drive systems where space constraints and acoustic noise are critical design parameters. The device consolidates multiple driver functions into a single integrated circuit to reduce board space and component count.
Replacement Considerations
The BH5510KVT-E2 is listed as Not Recommended for New Designs (NRND). Verify if the non-E2 variant BH5510KVT serves as a direct functional substitute or if alternative ROHM motor driver ICs are recommended for new implementations.
