BA5983FM-E2

Overview

The BA5983FM-E2 is a half-bridge driver IC manufactured by Rohm Semiconductor, designed for DC motor and general-purpose applications. It features an eight-channel output configuration with a peak current of 1A per channel. The device operates on a supply voltage range of 4.3V to 13.2V and supports a load voltage of 9V. Encased in a 28-HSOP-M package with two thermal pads, it functions within a temperature range of -35°C to 85°C. Key protection mechanisms include overtemperature shutdown. The component utilizes bipolar technology and interfaces via logic signals.

Feature Summary

• Eight-channel half-bridge driver architecture for multi-phase control
• Integrated overtemperature protection circuitry
• Logic interface compatibility for standard control systems

Applications

• DC motor control systems
• General-purpose driver circuits

Procurement Notes

Verify the current lifecycle status before procurement, as this component may be subject to discontinuation notices. Confirm that the 28-HSOP-M package dimensions and thermal pad requirements align with the target PCB layout. Ensure the operating voltage range meets system specifications. Check for RoHS3 compliance documentation if required by regulatory standards. Validate that the overtemperature protection thresholds are suitable for the intended thermal environment.

Selection Notes

Select this component when an eight-channel half-bridge topology is required for driving inductive loads such as DC motors. The bipolar technology and logic interface simplify integration with standard digital controllers. Consider the thermal performance of the 28-HSOP-M package with thermal pads for heat dissipation. Verify that the 1A output current per channel satisfies the load requirements. Evaluate the operating temperature range against environmental conditions.

Part Context

This part belongs to the BA5983 family of power management ICs from Rohm Semiconductor. It is classified under full-bridge and half-bridge drivers within the PMIC category. The device is distinct from other Rohm drivers like the BA5810FM-E2, which serves CD/CD-ROM drives, or linear regulators like the BD00KA5WFP-E2. Its specific eight-channel half-bridge design targets motor control rather than display or voltage regulation tasks.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Consult the manufacturer's Product Change Notification (PCN) or End-of-Life (EOL) notices for potential obsolescence management strategies. Direct pin-to-pin replacements should only be considered after verifying electrical parameter equivalence through official datasheets.
