MAX718ESE

Overview

The MAX718ESE is a specialized power management integrated circuit designed for palm-top computer and flash memory applications. Manufactured by Analog Devices Inc./Maxim Integrated, this component operates within a supply voltage range of 2.7V to 5.5V. It integrates multiple regulators including a step-down converter, a charge pump, and low-dropout regulators to support system requirements. The device is housed in a 16-pin SOIC package with an exposed pad for thermal dissipation. It features shutdown capability to minimize current consumption during standby modes, making it suitable for battery-powered portable electronics requiring efficient power regulation.

Feature Summary

• Integrates multiple voltage regulation functions including step-down, charge pump, and LDO regulators on a single chip
• Designed specifically for palm-top computers and flash memory power supply architectures
• Includes shutdown control to reduce quiescent current for extended battery life in portable devices

Applications

• Palm-top computer systems
• Flash memory power supply circuits
• Battery-operated portable electronic devices

Procurement Notes

Verify the exact suffix and tape/reel versus tube packaging options available from authorized distributors. Confirm RoHS compliance status and lead times as availability may vary. Ensure the supplier provides original manufacturer documentation to guarantee authenticity. Check for any specific ordering prefixes or suffixes that denote temperature ranges or packaging variations.

Selection Notes

Select this component when designing power systems for palm-top computers requiring integrated regulation. Consider the input voltage range and output current capabilities relative to the system load. Evaluate the thermal performance given the SOIC-16 package type. Compare against other Maxim PMICs if additional channels or different voltage levels are required for the specific application design.

Part Context

The MAX718 belongs to the Maxim Integrated family of power management ICs tailored for mobile computing. It consolidates several discrete power components into one solution to save board space. This series supports various configurations for notebook and handheld devices. The ESE suffix indicates a commercial temperature range and SOIC-16 package variant.

Replacement Considerations

Check for direct pin-compatible replacements within the MAX718 family such as MAX718CSE or MAX718UESE. Verify functional equivalence regarding regulator outputs and control interfaces before substitution.
