DS1640S

Power Distribution Switches, Load Drivers Overview

The DS1640S is a quad high-side power distribution switch manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 4.5V to 5.5V and supports load voltages from 3V to 5.5V. The device features four independent P-channel outputs, each capable of delivering up to 300mA. It utilizes a non-inverting open/switch interface for control. The component is housed in a 16-SOIC package with a width of 7.50mm and is rated for an operating temperature range of 0°C to 70°C.

Power Distribution Switches, Load Drivers Feature Summary

• Integrates four independent high-side power switches in a single compact package
• Features low on-resistance typical value of 67 milliohms for efficient power delivery
• Supports standard non-inverting logic input control for simple interfacing

Power Distribution Switches, Load Drivers Applications

• Power distribution systems requiring multiple isolated high-side switching channels
• Load driver circuits for peripheral devices in embedded systems
• Protection and control applications in industrial equipment operating at 5V logic levels

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix and tape-and-reel availability if continuous production is required. Confirm the 16-SOIC package dimensions match your PCB footprint constraints. Ensure the 0°C to 70°C commercial temperature rating aligns with your environmental requirements. Check for RoHS compliance status as per current manufacturer declarations.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when a quad-channel high-side switch is needed for 3V to 5.5V loads. The 300mA per channel limit defines the maximum load capacity. Consider the 67 milliohm on-resistance for thermal management calculations. The non-inverting interface simplifies control logic design compared to active-low alternatives.

Power Distribution Switches, Load Drivers Part Context

The DS1640S belongs to the Maxim Integrated power management family, specifically designed for load switching applications. It serves as a robust solution for managing multiple power rails in space-constrained designs. The SOIC-16 package offers a balance between pin count and board area efficiency for mid-density power distribution tasks.
