Overview
The BA5970FP-E2 is a four-channel bridge-tied load (BTL) driver manufactured by ROHM Semiconductor. Designed for driving CD player motors and actuators, it integrates an operational amplifier input stage with power output stages. The device operates within a supply voltage range of 4.5 V to 13.2 V. It features a 28-pin HSOP package with dimensions of 0.295 inches (7.50 mm) width and includes two heat tabs for thermal management. The component supports an operating temperature range from -35°C to +85°C.
Feature Summary
- Four-channel BTL driver architecture optimized for precision motor control applications
- Integrated operational amplifier input stage for signal conditioning
- Thermal management design utilizing dual heat tabs on the HSOP-28 package
Applications
- CD player spindle motor drive circuits
- Optical disc drive actuator control systems
- Precision small DC motor positioning applications
Procurement Notes
Verify the specific suffix E2 against the manufacturer's current datasheet to confirm compliance with RoHS directives and material composition requirements. Ensure the ordering part number matches the exact pin configuration and thermal pad specifications required by your PCB layout. Confirm that the HSOP-28 footprint aligns with the manufacturing capabilities of your assembly partner.
Selection Notes
Select this component when designing audio storage devices requiring precise multi-channel motor control. The integrated op-amp input simplifies interface circuitry compared to discrete solutions. Consider the thermal dissipation capabilities provided by the heat tabs if operating near the upper limits of the specified temperature range or current loads.
Part Context
This part belongs to ROHM's family of motor and motion controllers. It is specifically engineered for consumer electronics involving optical media players. The device replaces older discrete driver designs by integrating multiple channels into a single compact semiconductor solution, reducing board space and component count in portable audio equipment.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with direct replacements only through official ROHM cross-reference tools or authorized distributor substitution guides.
