What the TB6612FNG does
The TB6612FNG is a dual DC motor driver IC featuring LD MOS output transistors with low ON-resistance. It supports four operational modes including continuous forward and reverse rotation, short brake, and stop. The device handles a power supply voltage up to 15 V and delivers 1.2 A average output current per channel with a 3.2 A peak capability. It incorporates a standby power save system, built-in thermal shutdown, and low voltage detection. This component is typically used to control dual DC motors in applications requiring precise direction and speed management. It operates within a temperature range of -20 to 85 °C and utilizes a small SSOP24 package.
