MAX6958AAPE

Display Drivers Overview

The MAX6958AAPE+ is a compact multiplexed common-cathode display driver manufactured by Analog Devices Inc./Maxim Integrated. It interfaces microprocessors to seven-segment LED numeric displays or discrete LEDs via an SMBus and I2C-compatible two-wire serial interface. The device supports up to four digits of seven-segment displays with decimal points, along with four discrete LEDs. Key electrical parameters include a supply voltage range of 3V to 5.5V, a maximum supply current of 6.7mA, and a high-level output current of 30mA per segment. The low-level output current capability is 275mA. It operates within a temperature range of -40°C to +125°C and is housed in a 16-pin PDIP package.

Display Drivers Feature Summary

• Supports two-wire serial interface compatible with SMBus and I2C protocols for simplified microprocessor connectivity.
• Features internal hex decode logic and static RAM for storing display data, reducing processor overhead.
• Includes a 64-step digital brightness control circuit for adjusting LED illumination levels.
• Provides slew-rate-limited segment drivers to minimize electromagnetic interference (EMI).

Display Drivers Applications

• Audio and video equipment
• Industrial control panels
• Set-top boxes
• White home appliances

Display Drivers Procurement Notes

Verify the specific suffix 'AAPE+' against official Analog Devices documentation to confirm the exact grade and packaging configuration. Ensure compatibility with the target system's voltage levels and interface requirements before integration. Check for updated lifecycle status as distribution availability may vary.

Display Drivers Selection Notes

Select this component when a cost-effective solution for driving multiplexed seven-segment displays is required. It is suitable for applications needing direct interfacing with 2.5V or 3.3V logic systems while operating from a 5V supply. Consider the MAX6959 if keyboard input scanning capabilities are also needed.

Display Drivers Part Context

The MAX6958 belongs to a family of display drivers designed for common-cathode LED displays. It shares functional similarities with the MAX6959 but lacks the integrated keypad scanning features found in the latter. Both devices utilize the same 16-pin PDIP and QSOP packages and operate under similar electrical constraints.

Display Drivers Replacement Considerations

The MAX6959 is a pin-compatible alternative that includes additional keypad scanning functionality. Verify if the extra inputs are necessary or if they can be left unconnected. Other members of the MAX695x series may offer different digit counts or interface options.
