BA6219B

Overview

The BA6219B is a bipolar brush DC motor controller manufactured by Rohm Semiconductor. It integrates control and power stages for driving brushed DC motors with a maximum output current of 2A. The device operates within a supply voltage range of 8V to 18V and supports load voltages from 8V to 18V. It features an open/switch interface and utilizes a half-bridge output configuration consisting of two channels. The component is housed in a 10-HSIP package with a exposed tab for thermal management. It is designed for through-hole mounting and functions across a junction temperature range of -25°C to 150°C.

Feature Summary

• Integrates full driver, control logic, and power stage for simplified circuit design
• Supports bipolar brushed DC motor operation via dual half-bridge outputs
• Includes exposed thermal pad for efficient heat dissipation

Applications

• General purpose motor control systems
• Brushed DC motor drive circuits

Procurement Notes

Verify component status as the BA6219B is listed as obsolete or end-of-life in available records. Confirm availability of alternative packages such as the BFP variant if surface mount is required. Ensure design compatibility with existing through-hole manufacturing processes before finalizing procurement plans.

Selection Notes

Select this component for applications requiring integrated bipolar motor control with through-hole mounting constraints. Consider the 2A current limit and 8V-18V operating range when matching motor specifications. Evaluate thermal requirements due to the exposed tab design for adequate PCB heat sinking.
