TDE1798 is a high-output-current intelligent power switch. The output current can reach 500mA and can be short-circuit protected with a VCC of up to 35V. It also has internal thermal protection, external reset and synchronization capabilities. Open ground protection, output voltage can be lower than ground for fast inductive load demagnetization. Differential inputs for any logic system compatibility. Input voltage can be higher than VCC. Large supply voltage range from 6V to 35V. No need for external clamping diodes for demagnetization energy up to 150mJ. Several devices can be connected in parallel.
The TDE1798 is an interface circuit designed to deliver high currents capable of driving any type of load. It features built-in protection mechanisms including short-circuit protection against the positive supply or ground, as well as internal thermal protection that shuts down the driver if dissipation becomes too high.
The device operates over a wide range of supply voltages from 6V to 35V and includes differential inputs for logic system compatibility. Key features include open ground protection, the ability to handle demagnetization energy up to 150mJ without external clamping diodes, and the capability to connect several devices in parallel.
