MAX6951CEE+

The MAX6951CEE+ is a serially interfaced compact common-cathode LED Display Driver for bar graphs and matrix displays. The LED display driver that interface microprocessors to individual 7-segment numeric LED digits, bar graph or discrete LEDs through an SPI™-, QSPI™-, MICROWIRE™-compatible serial interface. The supply voltage can be as low as 2.7V. The MAX6951 drives up to eight 7-segment digits or 64 discrete LEDs. Included on-chip are hexadecimal character decoders (0-9, A-F), multiplex scan circuitry, segment and digit drivers and a static RAM that stores each digit. The user may select hexadecimal decoding or no-decode for each digit to allow any mix of 7-segment digits, bar graph or discrete LEDs to be driven. The segment current for the LEDs is set by an internal digital brightness control. The segment drivers are slew-rate limited to reduce EMI.
