The device features a half-bridge output structure capable of delivering up to 500mA output current. It utilizes DMOS technology and supports an SPI bus interface for control, including built-in EEPROM functionality. The circuit consumes approximately 2.8mA of operating current and supports a control input frequency of 300kHz. It is housed in a 28-pin VQFN package.

Feature Summary

• Fully integrated solution combining driver, control logic, and power stage for efficient operation
• Supports both stepper motors and brushed DC motors via bipolar drive architecture
• Enables detailed configuration through SPI bus interface with non-volatile memory storage

Applications

• Single-lens reflex (SLR) camera lens drivers
• Stepper motor control systems
• Brushed DC motor applications requiring low voltage operation

Procurement Notes

Verify the specific suffix E2 against the manufacturer's latest documentation to confirm environmental compliance status. Ensure the ordering quantity aligns with the standard tape and reel packaging requirements specified by Rohm Semiconductor. Confirm that the application voltage does not exceed the absolute maximum ratings defined in the official datasheet.

Selection Notes

Select this component when a low-voltage system between 2.7V and 3.6V requires integrated motor control without external power transistors. The built-in EEPROM allows for persistent configuration settings, reducing external memory requirements. It is suitable for space-constrained designs due to the compact VQFN package and high integration level.

Part Context

This part belongs to Rohm Semiconductor's family of motor controllers and drivers. It is categorized under PMIC solutions for motion control. The device integrates digital control interfaces with analog power stages, targeting portable electronics and imaging devices where power efficiency and board space are critical constraints.

Replacement Considerations

Consult the official replacement guide for direct pin-compatible alternatives. Verify that any substitute maintains the same voltage range and output current capabilities. Ensure the replacement supports the required SPI interface protocol if software compatibility is a constraint.
