BD65496MUV Single Brushed DC Motor Driver Carrier
The BD65496MUV from ROHM is a tiny H-bridge motor driver IC that can be used for bidirectional control of one brushed DC motor at 2V to 16V. It can supply up to about 1.2A continuously and can tolerate peak currents up to 5A for a few milliseconds. The BD65496MUV is a great IC, but its small surface-mount package makes it difficult for the typical student or hobbyist to use; our breakout board makes it easy to use with standard solderless breadboards and 0.1″ perfboards. Since this board is a carrier for the BD65496MUV, we recommend careful reading of the BD65496MUV datasheet (481k pdf). The board ships populated with SMD components, including the BD65496MUV and a reverse battery protection circuit.
Features
- Single-channel H-bridge motor driver with shoot-through protection and internal free-wheeling diodes (can drive one DC motor)
- Motor supply voltage: 2V to 16V
- Logic supply voltage: 2.5V to 5.5V
- Output current: up to 1.2A continuous (5A peak for a few milliseconds)
- Two possible interface modes: IN/IN or EN/IN (one pin for speed and another for direction)
- Configurable switching speed allows for PWM frequencies up to 500kHz
- Under-voltage lockout on the logic supply and protection against over-temperature
- Carrier board adds reverse-voltage protection on the motor supply
- Compact size (0.6″×0.6″)
Included hardware
Two 1×6-pin breakaway 0.1″ male headers are included with the BD65496MUV motor driver carrier, which can be soldered in to use the driver with breadboards, perfboards, or 0.1″ female connectors. (The headers might ship as a single 1×12 piece that can be broken in half.) The right picture above shows the two possible board orientations when used with these header pins (parts visible or silkscreen visible). You can also solder your motor leads and other connections directly to the board.
