BD6231F-E2

The ROHM BD6231F-E2 is a versatile H-bridge driver IC specifically designed for brush motor applications. It operates within a wide power supply voltage range, from 6V to 32V, and can deliver output currents up to 2A. The integrated MOS transistors enable efficient PWM speed control, while the VREF voltage control function allows for direct replacement of discontinued motor driver ICs. This highly efficient driver facilitates low-power consumption designs.

Key electrical specifications include a maximum supply voltage of 36V, maximum output currents of 0.5A, 1.0A, and 2.0A, and an output ON-resistance of 1.5Ω or 1.0Ω depending on the variant. The PWM input frequency range is from 20kHz to 100kHz, with a typical standby current of 0μA. The device operates across a temperature range of -40°C to +85°C.

This driver IC is available in the SOP8 package, measuring 5.00mm x 6.20mm x 1.71mm, and is supplied on embossed tape and reel for surface mounting. It includes built-in selectable one or two-channel configurations, a cross-conduction prevention circuit, and four protection circuits: OCP, OVP, TSD, and UVLO.

Applications for the BD6231F-E2 include VTRs, CD/DVD players, audio-visual equipment, optical disc drives, PC peripherals, and OA equipment.
