Frequently Asked Questions
What continuous and peak output current can TDE1897RFPT sink per channel?
TDE1897RFPT supports a continuous output sink current of 500 mA and a peak current limit of 750 mA per channel. These ratings allow it to drive relay coils, solenoids, and LED arrays reliably. The integrated over-current protection clamps output current to prevent damage when loads exceed the rated limit.
How does TDE1897RFPT interface with a 3.3 V or 5 V MCU logic signal?
TDE1897RFPT uses a buffer/inverter-based input stage compatible with standard 3.3 V and 5 V CMOS/TTL logic levels. The input threshold is typically below 1.5 V for logic-low recognition, meaning a standard MCU GPIO pin can directly control the driver without level-shifting circuitry, simplifying board design and reducing component count.
What built-in protection features does TDE1897RFPT include, and how do they operate?
TDE1897RFPT integrates three hardware protections: over-current limiting that caps output at 750 mA peak, thermal shutdown that disables the output above approximately 170°C junction temperature, and under-voltage lockout that prevents operation below the minimum supply threshold. These features protect both the IC and connected loads from fault conditions without requiring external components.
In which industrial or automotive applications is TDE1897RFPT commonly specified?
TDE1897RFPT is frequently specified in PLC digital output modules, industrial motor starters, solenoid valve drivers in fluid control systems, and relay drivers in building automation panels. Its 500 mA continuous sink capability and 20-pin SO-20 package support multi-channel output board designs at 12 V to 24 V supply voltages commonly used in these environments.
