Additional Details

The TD62381FNG contains multiple independent source driver channels. Each channel incorporates an input, an output, and a clamping diode connected between the output and the supply voltage. These diodes are critical for suppressing voltage spikes caused by inductive loads during switching operations. The device is designed for compatibility with both TTL and 5V CMOS logic levels, making it versatile for different control circuit applications. The low saturation voltage helps ensure efficient power delivery to the load while minimizing power dissipation. The TD62381FNG is typically available in a surface mount package like a SOL (Small Outline Large) package. The operating temperature range typically spans from -40°C to +85°C.
