Driving 4-1/2 Digit Counter Displays with the MAX6958/59 LED
Drivers

Abstract: This application note provides details on how to connect the MAX6958 and MAX6959 LED display
drivers to 5-digit LED displays for counter display applications requiring the display range -39999 to 39999
without decimal points.


The MAX6958 and MAX6959 are 4-digit, 9-segment LED drivers which use a reduced pin count multiplexing
scheme to drive 36 segments using only 10 drive pins (Table 1). This application note discusses a technique to
drive a 5th, additional digit. A 5th digit is required for counter display applicat……
