MAX6958, MAX6959 2-Wire Interfaced, 3V To 5.5V, 4-Digit, 9-Segment LED Display Drivers With Keyscan

The MAX6958 MAX6959 compact multiplexed common- cathode Display drivers Interface Microprocessors to seven-segment numeric LED digits, or Discrete LEDs through an SMBus- and IC-compatible 2-wire serial Interface The 2-wire serial Interface uses fixed 0.8V/2.1V Logic thresholds for compatibility with 2.5V and 3.3V systems when the Display driver is powered from a 5V supply.
The MAX6958 MAX6959 drive up to four 7-segment digits, with decimal points, plus four Discrete LEDs or four 7-segment digits and eight Discrete LEDs if the digits' decimal points are not used, or up to 36 Discrete LEDs The MAX6959 also includes two input ports, one or both of which may be configured as a key-switch reader, which automatically scans and debounces a matrix of up to eight switches. Key-switch status is obtained by polling internal status Registers or by configuring the MAX6959 interrupt output.
Other on-chip features include a hexadecimal font for seven-segment Displays multiplex scan circuitry, anode and cathode drivers, and static RAM that stores each digit. The peak segment current for the Display digits is set internally to 23mA. Display intensity is adjusted using a 64-step internal digital brightness control. The MAX6958 MAX6959 include a low-power shutdown mode, a scan-limit Register that allows the user to Display from one to four digits, and a test mode, which forces all LEDs on. The LED Drivers are slew-rate-limited to reduce EMI
The MAX6958 MAX6959 are available in 16-pin PDIP and QSOP packages and are fully specified over the -40C to +125C automotive temperature range.
