TDE1798DP

TDE1798DP is a 0.5A intelligent power switch. The TDE1798 is an interface circuit delivering high currents and is capable of driving any type of load. The output is protected from short circuits with the positive supply or ground. In addition, thermal shutdown is provided to keep the IC from overheating. If internal dissipation becomes too high, the driver will shut down to prevent excessive heating. The output stays null after the overload is off if the reset input is low. If high, the output will alternatively switch on and off until the overload is removed. The device operates over a wide range of supply voltages from standard ±15 operational amplifier supplies to the single ±6V or +35V used for industrial electronic systems. Input voltage can be higher than the VCC. The output is low in open ground conditions.

• High output current is 500mA
• Short-circuit protection up to VCC = +35V
• Internal thermal protection with external reset and synchronization capability
• Open ground protection, sink and source alarm outputs
• Output voltage can be lower than ground for fast inductive load demagnetization
• Differential inputs for any logic system compatibility
• Several devices can be connected in parallel
• Input offset voltage is 2mV typical
• Operating ambient temperature range from -25 to 85°C
• Minidip package
