BD65491FV-E2

Overview

The BD65491FV-E2 is a single-channel brushed DC motor driver IC from ROHM Semiconductor, housed in a 16-pin SSOP-B surface-mount package. It features an H-bridge configuration with a maximum output current of 1.2 A and a peak current capability of 3.2 A to 4.0 A depending on the source. The device operates within a power supply voltage range of 1.8 V to 16 V for the load and 2.5 V to 5.5 V for logic. Key electrical parameters include a typical on-resistance of 0.35 Ω, a quiescent current of 1.3 mA, and a power dissipation rating of 870 mW. The operating temperature range spans from -30°C to +85°C.

Feature Summary

• Integrates a full-on drive H-bridge with P-channel DMOS upper switches, eliminating the need for a charge pump.
• Supports high-speed switching with selectable turn-on and turn-off times to optimize performance.
• Includes built-in under-voltage lockout (UVLO) and thermal protection circuits to prevent malfunction.
• Features low standby current consumption, typically 0 μA when disabled.

Applications

• Portable electronic devices requiring compact motor control solutions
• Home appliance fan and pump motors
• Small robotic actuators
• Industrial automation equipment

Procurement Notes

Verify the specific suffix 'E2' against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Ensure the ordering quantity aligns with the standard taping packaging quantity of 2500 units. Confirm that the application voltage does not exceed the 16 V load limit or the 20 V absolute maximum rating for Vcc.

Selection Notes

Select this component for applications requiring a single H-bridge driver with low standby current and wide input voltage flexibility. It is suitable for systems operating at 1.8 V logic levels without external level shifting. Consider the thermal dissipation capabilities given the 870 mW power rating and ensure adequate PCB copper area for heat spreading.

Part Context

This part belongs to the BD65491 series of motor drivers designed for portable and home appliance applications. It is distinct from the BD65492, which offers two channels. The series emphasizes low power consumption and small footprint, utilizing SSOP-B16 packaging to fit space-constrained designs while maintaining robust motor driving capabilities.

Replacement Considerations

The BD65491FV is listed as an alias for this part number. No other direct substitute part numbers are confirmed in the provided documentation. Verify cross-compatibility with any alternative single-channel H-bridge drivers by comparing pin assignments, current ratings, and package dimensions.
