The TDE1897C/TDE1898C is a monolithic Intelligent Power Switch in Multipower BCD Technology, for driving inductive or resistive loads. An internal Clamping Diode enables the fast demagnetization of inductive loads. Diagnostic for CPU feedback and extensive use of electrical protections make this device inherently indistructible and suitable for general purpose industrial applications.

The TDE3247 is a monolithic amplifier designed for high current and high voltage applications, specifically to drive lamps, relays and stepping motors. The Device is essentialy blow-out proof. Current limiting is available to limit the peak output current to a safe value, the adjustment only required an external resistor. In addition, thermal shut-down is provided to keep the IC from overheating. If external dissipation becomes too high, the driver will shut-down to prevent excessive heating. The output is also protected against short-circuit with the positive power supply. The device operates over a wide range of supply voltage from standard ±15V operational amplifier supplies down to the single 12V or 24V used for industrial electronic systems.
