Summary of CLT03-1SC3 DIGITAL INPUT CURRENT LIMITER
The CLT03 series is a digital input current limiter that reduces power dissipation by activating only when an input signal is present and consuming no power when off. It supports high-side and low-side connections, reverse plugin compatibility, drives optocouplers or 3.3 V LVTTL inputs, meets IEC 61131-2 type 1 and 3 characteristics, includes a deglitch filter for EMC robustness, and is available in single and dual isolated channel devices and two package options.
Parts used in the CLT03 series project:
- CLT03-1SC3 device (single channel option)
- CLT03-2Q3 device (dual channel option)
- STEVAL-IFP035V1 evaluation board (for CLT03-2Q3)
- Opto-coupler (for isolated digital input drive)
- 3.3 V LVTTL digital input circuit (for non-isolated drive)
- SOT23-8L package (650 µm pitch option)
- QFN-16L package (500 µm pitch option)
The CLT03 series is a digital input current limiter which drastically reduces the power dissipation of the digital inputs. It does not require external power supply as the device is activated with the input signal and it consumes no power in off state.
The CLT03 series is high side and low side compatible, as well as reverse plugin compatible. It can drive either opto-coupler or 3.3 V LVTTL circuit.
The CLT03-2Q3 can be evaluated thanks to the STEVAL-IFP035V1 evaluation board which embeds an isolated and non-isolated digital inputs configuration.
