Additional Details

The TD62385AF consists of eight independent sink driver channels, each with an output clamp diode for protection against voltage spikes when driving inductive loads. It is housed in a SO-16 package. The input pins are designed for compatibility with both TTL and 5V CMOS logic levels. The built-in thermal shutdown feature protects the device by disabling the outputs when the junction temperature exceeds a safe limit. Overcurrent protection is also included to limit the output current and prevent damage to the device and the load in case of short circuits or excessive current draw. The TD62385AF is suitable for use in a variety of industrial and automotive applications where robust and reliable driving of inductive loads is required.
