DS1336S

Overview

The DS1336S is an OR controller and source selector switch manufactured by Analog Devices Inc./Maxim Integrated. It features a 5:5 input-to-output ratio with internal switches, designed for battery backup, industrial, automotive, and high-current switching applications. The device operates within a supply voltage range of 3V to 5.5V and consumes 250 µA of supply current. It delivers a maximum output current of 300mA with an on-delay time of 100 ns. Packaged in a 16-SOIC (0.154", 3.90mm wide) surface-mount format, it supports through-hole or surface-mount installation types depending on the specific variant configuration, operating reliably between 0°C and 70°C.

Feature Summary

• Functions as an OR controller and source selector switch for power path management
• Provides five independent input channels with corresponding outputs for flexible power routing
• Integrates internal switches to facilitate seamless source selection without external components

Applications

• Battery backup systems requiring automatic source switching
• Industrial equipment power management circuits
• Automotive grade electronic systems needing reliable power redundancy
• High-current switching applications involving multiple power sources

Procurement Notes

Verify component authenticity through authorized distributors due to discontinuation status. Confirm package type matches design requirements as variants exist. Check RoHS compliance documentation carefully since some listings indicate non-compliance. Ensure supply chain stability given potential obsolescence risks associated with older Maxim Integrated product lines.

Selection Notes

Select this component when designing systems requiring redundant power inputs with automatic OR-ing functionality. Consider the 300mA output limit and 100ns delay characteristics against system timing requirements. Evaluate thermal performance within the specified operating temperature range. Verify compatibility with available supply voltages between 3V and 5.5V before integration into final designs.

Part Context

The DS1336 belongs to Maxim Integrated's portfolio of power management integrated circuits focused on source selection and protection. As part of the broader PMIC category, it addresses needs for multi-source power architectures common in portable and critical infrastructure electronics. The SOIC packaging variant offers space-efficient mounting solutions for modern printed circuit board layouts while maintaining robust electrical isolation between input sources.
