Overview
The RT7322CGGSP is a linear LED driver IC manufactured by Richtek USA Inc., designed for low-power lighting applications. It provides a single constant current output capable of up to 20mA, suitable for driving single-color or RGB LEDs. The component operates within a junction temperature range of -40°C to +125°C and is housed in an 8-pin SOP package with an exposed pad (SOP-EP-8). As a linear regulator, it offers precise current control without the complexity of switching topologies.
Feature Summary
- Provides stable constant current regulation for LED loads
- Supports operation across extended industrial temperature ranges
- Compact surface-mount packaging facilitates automated assembly
Applications
- Single-color LED indicator circuits
- Low-power RGB LED channel driving
- General-purpose LED status indication
Procurement Notes
Verify the specific suffix 'GGSP' against the official Richtek datasheet to confirm pinout compatibility and thermal performance specifications. Ensure that the required drive current does not exceed the 20mA limit defined in the electrical characteristics. Confirm RoHS compliance status through the manufacturer's declaration before integration into regulated assemblies.
Selection Notes
Select this component when a simple, cost-effective solution for low-current LED driving is required. Linear topology is preferred over switching regulators for noise-sensitive applications where electromagnetic interference must be minimized. Evaluate thermal dissipation requirements based on the voltage drop across the device and the maximum 20mA output constraint.
Part Context
This part belongs to the Richtek PMIC portfolio, specifically within the LED Driver subcategory. It complements higher-power switching solutions like the RT7233 series by addressing niche low-current requirements. The device utilizes standard SOP-EP-8 packaging common to Richtek's small-signal power management lineup.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify cross-reference data directly with Richtek technical support if alternative sourcing is necessary.
