BU24032GW-E2

Overview

The BU24032GW-E2 is a half-bridge motor controller manufactured by ROHM Semiconductor, designed for portable equipment applications. It operates within a supply voltage range of 2.7 V to 3.6 V and delivers an output current of 500 mA. The device features a low operating supply current of 4 mA and functions reliably across a temperature range of -20°C to +85°C. Packaged in SMD/SMT format with options for Reel or Cut Tape, this component integrates motor drive capabilities into a compact form factor suitable for space-constrained designs.

Feature Summary

• Integrates half-bridge driver topology for efficient motor control
• Optimized for low power consumption in portable devices
• Supports surface mount installation for automated assembly

Applications

• Portable electronic equipment motor drives
• Fan and motion control systems
• Ignition controllers for small appliances

Procurement Notes

This component is currently listed as obsolete or end-of-life by the manufacturer. Availability is restricted, and sourcing may require checking secondary market distributors or verifying specific stock conditions. Engineers should consider design-in alternatives early to mitigate supply chain risks associated with discontinued parts.

Selection Notes

Select this part when a single-channel half-bridge driver is required for low-voltage portable applications. Ensure the system voltage remains within the 2.7 V to 3.6 V range and that the thermal environment stays between -20°C and +85°C. Verify that the 500 mA output current meets the load requirements without exceeding thermal limits.

Part Context

The BU24032GW-E2 belongs to ROHM's portfolio of motor and motion controllers, specifically targeting the PMIC category for power management in small electronics. It complements other drivers in the series by offering a balance of performance and size for consumer-grade portable devices requiring simple bidirectional motor control.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, engineers should consult official ROHM replacement guides or contact authorized distributors for direct cross-reference recommendations based on specific electrical and mechanical constraints.
