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 document details the TDE1897C and TDE1898C, which are monolithic Intelligent Power Switches designed using Multipower BCD technology to drive inductive or resistive loads. Key features include an internal clamping diode for fast demagnetization of inductive loads, open ground protection, and under-voltage lockout with hysteresis.
| Output Current | 0.5A |
|---|---|
| Supply Voltage Range | 18V to 35V |
| Operating Temperature Range | -25 to +85 °C |
| Short Circuit Current | 0.75 A to 1.5 A |
| Internal Voltage Clamp | 45 V to 55 V |
The device can absorb a maximum of 200 mJ from an inductive load at a junction temperature of 85°C.
It uses an internal clamping diode that limits the voltage across the Power MOS to between 45 and 55V.
Valid diagnostics require a minimum supply voltage of 9V, with an operative range between 18V and 35V.
