Frequently Asked Questions
What is the LM27964SQ-C and what is it used for?
The LM27964SQ-C is a serial-interface white LED driver IC from Texas Instruments, designed primarily for LCD backlight applications. It supports up to 6 LED segments, uses a SPI-compatible serial data input, and is housed in a compact 24-pin QFN package, making it ideal for portable consumer electronics and space-constrained designs.
What interface does the LM27964SQ-C use to communicate with a microcontroller?
The LM27964SQ-C uses a serial (SPI-compatible) data input interface for communication with a host microcontroller. This simplifies PCB routing and reduces the number of control lines needed compared to parallel interface drivers, making integration straightforward in embedded system designs.
What package does the LM27964SQ-C come in, and is it RoHS compliant?
The LM27964SQ-C is available in a 24-pin QFN package (JESD-30 code S-XQCC-N24). It is fully RoHS compliant with a Pb-free construction rated under JESD-609 code e3, making it suitable for modern environmentally-regulated consumer and industrial electronics applications.
Can the LM27964SQ-C drive multiple LED segments simultaneously?
Yes, the LM27964SQ-C supports up to 6 LED segments. However, it does not support multiplexed display capability, meaning each segment is driven directly. This design ensures consistent brightness and simplified control for white LED backlight applications in LCD panels.
