Overview
The CAT4101TV-T75 is a single-channel, non-isolated LED driver IC manufactured by onsemi. It operates within an input voltage range of 3V to 5.5V and provides a constant output current of 1A per channel. The device features adjustable brightness control via an external resistor connected to the SET pin. It is housed in a compact SOT-23-6 surface-mount package, designed for efficient thermal performance and space-constrained applications.
Feature Summary
- Provides a regulated 1A constant current output for driving high-power LEDs
- Supports dimming functionality through an external resistor setting
- Operates with a wide input voltage range from 3V to 5.5V
Applications
- Portable device backlighting
- General illumination systems
- LED indicator circuits
Procurement Notes
Verify the specific suffix 'T75' against the official datasheet to confirm tape-and-reel packaging specifications. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm that the operating temperature range aligns with your system's environmental constraints.
Selection Notes
Select this component when a single-channel, high-current LED driver is required within a low-voltage supply environment. It is suitable for designs needing precise current regulation without complex PWM control interfaces. Consider the SOT-23-6 package size for PCB layout limitations. Evaluate thermal dissipation needs as the device handles up to 1A output current.
Part Context
This part belongs to the CAT4101 family of LED drivers from onsemi. The family includes variants such as the CAT4101AEVB evaluation board and other channel configurations like the CAT4104. These devices are designed for simple, cost-effective LED lighting solutions requiring constant current regulation.
Replacement Considerations
Check for direct substitutes within the same product family or comparable single-channel LED drivers from other manufacturers. Verify pin compatibility and electrical specifications before substitution.
