Product details

What the MAX6951EEE+ is and where it fits

The Maxim Integrated MAX6951EEE+ is a dedicated LED display driver IC designed to control 8 digits of 7-segment LED displays through a 3-wire serial interface. It handles the multiplexing, current regulation, and BCD-to-7-segment decoding internally, offloading the host microcontroller from real-time display refresh. The 2.7V to 5.5V supply range lets it run from either a 3.3V or 5V rail without an extra regulator, and the -40°C to 85°C industrial temperature grade suits it for equipment enclosures, panel meters, and industrial control panels where the ambient temperature swings.

8-digit drive and the 3-wire serial interface

Eight digits of 7-segment drive is the headline capacity — that covers a typical 8-digit numeric readout or four 2-digit modules daisy-chained. The 3-wire serial interface (clock, data, load) is SPI-compatible at the protocol level, so any MCU with a spare SPI port or three GPIOs can talk to it. The part draws 10 mA supply current typical, which includes the internal oscillator and the segment drivers; the LED current itself comes from the supply rail through the external resistors, not through the IC's own supply pin.

Package and mounting

The MAX6951EEE+ is supplied in a 16-pin QSOP package (the supplier device package is 16-QSOP, the industry-standard package / case is 16-SSOP with 0.154-inch body width and 3.90 mm width). It is a surface-mount part intended for reflow assembly. The Tube shipping medium means the parts arrive in anti-static tubes, not tape-and-reel — factor that into your pick-and-place feeder setup if you are running high volume.

Lifecycle and sourcing reality

The part is ROHS3 compliant. For BOM planning, there is no last-time-buy risk today, and no forced redesign window.

Frequently asked questions

Does MAX6951EEE+ require external resistors?

Yes, the MAX6951EEE+ requires external current-setting resistors on the segment outputs to limit LED current. The part handles the multiplexing and decoding, but the peak segment current is set by the resistor value chosen for the LED forward voltage and desired brightness.

MAX6951EEE+ vs MAX6952: which is better?

The MAX6952 is the higher-integration sibling that adds a 16-pin QSOP package and includes a 4-wire serial interface with a SPI/QSPI-compatible mode, plus a wider 2.7V to 5.5V supply range identical to the MAX6951. The key difference is the MAX6952 supports a higher segment current capability and includes a blink function. For a basic 8-digit 7-segment application without blink, the MAX6951EEE+ is the cost-optimized choice; the MAX6952 adds features but at a higher unit cost.
