SP7121EK-F/TR

Overview

The SP7121EK-F/TR is a dual-channel linear LED driver IC manufactured by MaxLinear, Inc. It provides independent current regulation for two LED segments with an output current capability of up to 25mA per channel. The device operates within a supply voltage range of 2.7V to 5.5V and supports PWM dimming control. It is housed in a compact SOT-23-6 package and functions across an operating temperature range of -40°C to +85°C.

Feature Summary

Dual-channel linear topology for independent LED segment control
Supports Pulse Width Modulation (PWM) dimming functionality
Compact SOT-23-6 surface-mount package design

Applications

Backlighting for portable electronic devices
Indicator lighting in consumer electronics
General-purpose LED segment illumination

Procurement Notes

Verify the manufacturer designation on the datasheet, as historical records indicate Exar Corporation as the original source before acquisition by MaxLinear. Confirm that the specific suffix matches the required packaging format. Ensure compatibility with the target system's voltage levels and thermal requirements before finalizing procurement.

Selection Notes

Select this component when a dual-channel solution is required for low-current LED applications. It is suitable for designs needing linear regulation rather than switching topologies. Consider the SOT-23-6 footprint constraints and the 25mA per channel limit when determining suitability for the intended load.

Part Context

This part belongs to the LED driver category within MaxLinear's portfolio. It serves as a successor or equivalent to parts previously distributed under the Exar brand name. The device addresses the need for simple, cost-effective current regulation in space-constrained mobile and handheld applications.

Replacement Considerations

Cross-reference with other MaxLinear dual-channel LED drivers if pinout compatibility is critical. Verify electrical parameters against legacy Exar equivalents if replacing older designs. Ensure the replacement maintains the same SOT-23-6 package dimensions.
