Overview
The BD61245EFV-E2 is a multifunction single-phase full-wave fan motor driver by ROHM Semiconductor. It integrates an H-bridge power DMOS FET and control circuitry into a single chip. The device supports PWM soft switching with a drive current of 1.8A. It operates within a temperature range of -40°C to 105°C (TA). The component is housed in a 16-VSSOP package with an exposed pad, specifically identified as HTSSOP-B16 or 16-VSSOP (0.173", 4.40mm Width).
Feature Summary
- Integrates H-bridge power DMOS FETs for single-chip operation.
- Supports PWM soft switching technology for efficient drive control.
- Provides multifunctional capabilities for single-phase full-wave fan motors.
Applications
- Single-phase DC brushless fan motor drives
- Full-wave fan motor control systems
- Appliance cooling fans
Procurement Notes
Verify the exact suffix E2 against the manufacturer's latest datasheet to confirm pinout and electrical specifications match the design requirements. Ensure the 16-VSSOP footprint aligns with the PCB layout. Confirm RoHS compliance status if required by the end product regulations. Cross-reference the operating temperature range with the intended environmental conditions.
Selection Notes
Select this component for applications requiring a compact solution for single-phase fan motors. The integrated DMOS FET reduces external component count. Verify that the 1.8A drive capability meets the motor load requirements. Consider the thermal performance of the exposed pad package for heat dissipation in enclosed spaces.
Part Context
This part belongs to ROHM's series of multifunction single-phase full-wave fan motor drivers. It is designed to replace discrete solutions by combining power and logic functions. The family includes variants with different input signal options such as DC, PWM, FG, and AL signals.
Replacement Considerations
Check for direct substitutes like BD61250MUV or BD69740FV if different speed control inputs are needed. Verify compatibility with existing control signals before substitution.
