Overview
The SP7612AEC6-L is a low dropout linear LED driver designed for parallel-connected LEDs. It provides matched current sources for any color LED, with the maximum steady-state current per LED rated at 40mA. The device features integrated PWM and analog brightness control alongside an enable/shutdown pin that reduces shutdown current to less than 0.01µA. It operates without EMI or switching noise and is available in tiny, RoHS-compliant lead-free SC-70 packages.
Feature Summary
- Provides matched current sources for parallel-connected LEDs of any color
- Integrates both PWM and analog brightness control capabilities
- Features passive shutdown with extremely low standby current consumption
Applications
- Handset keyboard backlighting
- PDA and DSC display modules
- MP3 player LCD backlighting
- Handheld computer displays
Procurement Notes
Verify the specific suffix 'L' against the manufacturer's official documentation to confirm package type and compliance status. Ensure the design accounts for the requirement that LED1 must always be connected to prevent open-circuit errors in other channels. Confirm thermal performance within the SC-70 package constraints for the intended application load.
Selection Notes
Select this component when driving multiple parallel LEDs requiring precise current matching without switching noise. It is suitable for battery-powered portable devices where low quiescent current during shutdown is critical. Consider the 40mA per channel limit and the necessity of connecting LED1 to ensure proper operation of all channels.
Part Context
This part belongs to the SP7612/SP7614 family of low dropout linear LED drivers manufactured by Exar (now part of MaxLinear). The SP7612 variant specifically supports three parallel LED channels, whereas the SP7614 supports two. These drivers are engineered for cost-sensitive portable electronics applications requiring simple external resistor programming for current setting.
Replacement Considerations
Consult official substitution lists for equivalent low-dropout LED drivers from the same manufacturer family. Verify channel count compatibility, as the SP7614 offers a two-channel alternative. Ensure replacement parts maintain the required shutdown current specifications and package footprint if board space is constrained.
