LED1642GWQTR

Overview

The LED1642GWQTR is a monolithic, low-voltage, low-current power 16-bit shift register designed for LED panel displays. It features 16 constant current output channels with an output current ranging from 3 mA to 40 mA, programmable via an external resistor. The device includes 7-bit global current gain control and supports 12/16-bit PWM brightness control. It operates within a supply voltage range of 3 V to 5.5 V, with a maximum output voltage of 20 V. The internal switch frequency reaches 30 MHz. It is housed in a 24-pin QFN package and meets AEC-Q100 qualification standards.

Feature Summary

Integrates 16 constant current output channels with error detection capabilities
Supports 12/16-bit PWM dimming for precise brightness control
Features programmable output current via external resistor
Includes 7-bit global current gain adjustment

Applications

LED panel displays
Signage lighting
Direct drive LED matrices

Procurement Notes

Verify the specific suffix 'QTR' corresponds to the 24-QFN package and tape-and-reel packaging configuration. Confirm that the component meets AEC-Q100 automotive qualification requirements if intended for automotive applications. Ensure the external resistor selection aligns with the required 3 mA to 40 mA output current range specified in the datasheet.

Selection Notes

Select this component for applications requiring direct drive of LED panels with integrated shift register functionality. Consider the 24-QFN package size for space-constrained designs. Evaluate the need for 16-bit resolution versus 12-bit PWM control based on display quality requirements. Verify compatibility with the system's logic voltage levels within the 3 V to 5.5 V operating range.

Part Context

The LED1642GW series belongs to STMicroelectronics' family of LED driver ICs designed for high-density display applications. This specific variant integrates power stages and control logic into a single monolithic solution, reducing component count compared to discrete driver implementations. It serves as a key interface between digital control systems and LED arrays.

Replacement Considerations

Check for pin-compatible alternatives within the same product family. Verify electrical parameter equivalence for output current and voltage ratings when substituting.
