DS1336SN

Overview

The DS1336SN 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 and industrial applications. The device operates within a supply voltage range of 3V to 5.5V and draws a supply current of 250 µA. It supports a maximum output current of 300mA and exhibits an open delay time of 100 ns. The component is housed in a 16-SOIC package (0.154 inch width) and is rated for operation between 0°C and 70°C.

Feature Summary

• Functions as an OR controller and source selector switch for power management systems.
• Provides five independent input channels routed to five corresponding output channels.
• Integrates internal switching mechanisms to manage power source selection automatically.

Applications

• Battery backup systems requiring seamless power source transition
• Industrial equipment power management circuits
• Automotive grade electronic systems

Procurement Notes

Verify the specific suffix SN indicates the SOIC surface-mount package configuration. Confirm the operating temperature range matches the 0°C to 70°C specification for your environment. Ensure the supply voltage remains within the 3V to 5.5V limits. Check for RoHS compliance status as some variants may differ. Validate that the 300mA output current capacity meets your load requirements.

Selection Notes

Select this component when a multi-channel power source selection mechanism is required. It is suitable for designs needing to combine multiple power inputs into separate outputs. Consider the 250 µA supply current for low-power standby modes. The 100 ns delay time should be evaluated against system response requirements. Ensure the 16-SOIC footprint fits the PCB layout constraints.

Part Context

This part belongs to the Maxim Integrated portfolio, now under Analog Devices Inc. It serves as a specialized power management IC distinct from their real-time clocks or data converters. The DS1336 series focuses on ideal diode and OR controller functionalities for robust power distribution architectures.
