Details
GENERAL DESCRIPTION The DS2413 is a dual-channel programmable I/O 1-Wire® chip. The PIO outputs are configured as open drain and provide up to 20mA continuous sink capability and off-state operating voltage up to 28V. Control and sensing of the PIO pins is performed with a dedicated device-level command protocol. To provide a high level of fault tolerance in the end application, the 1-Wire IO and PIO pins are all capable of withstanding continuous application of voltages up to 28V max. Communication and operation of the DS2413 is performed with the single contact Maxim/Dallas 1-Wire serial interface.FEATURES ■ Open-Drain Programmable I/O Pins ■ PIO Pins Support 20mA max Continuous Current Sink ■ Supports 28V (max) PIO Pin Operating Voltage ■ On-Resistance of PIO Pulldown Transistor 20Ω max; OFF Resistance 1MΩ min ■ Parasitic Power Supply Through 1-Wire ■ Communicates to Host with a Single Digital Signal at 14.9kb or 100kbps Using 1-Wire Protocol ■ Unique 64-bit ROM Serial Number Factory Lasered Into Each Device ■ Switchpoint Hysteresis and Filtering to Optimize Performance in the Presence of Noise ■ 1-Wire IO Pin Supports 28V Absolute Maximum DC Level for Fault Conditions ■ Operates Over a Wide 1-Wire Voltage Range of 2.8V to 5.25V from 0°C to +70°C ■ High ESD Immunity of 1-Wire IO Pin: 8kV HBM Typical ■ TSOC and TDFN Packages AvailableAPPLICATIONS ■ LED Control ■ Accessory Identification and Control ■ General Purpose Input/Output ■ Key-Pick Systems ■ Industrial Controllers ■ System Monitoring

FAQs
What is DS2413P+?
The DS2413P+ is a dual-channel I/O port expander integrated circuit designed by Maxim Integrated. It provides two open-drain I/O ports that can be controlled and monitored using a 1-wire protocol, making it suitable for applications requiring remote I/O expansion and control.
How Does DS2413P+ Work?
The DS2413P+ works by expanding the I/O capabilities of a microcontroller or microprocessor through its open-drain I/O ports. It communicates with the host system using the 1-wire protocol, enabling remote control and monitoring of attached devices or sensors. The device can be powered directly through the 1-wire interface, simplifying installation and operation in remote locations.
How Many Pins does DS2413P+ have and What are the Functions of the Pinout Configuration?
The DS2413P+ is housed in a 6-pin TSOC (Thin Small Outline Package) package. The pinout configuration includes:
- GND: Ground pin.
- DQ: 1-wire data input/output pin.
- VDD: Power supply pin.
- PIOA: Port A I/O pin.
- PIOB: Port B I/O pin.
- VDD2: Power supply for overdrive pin.
What are the Pros and Cons of DS2413P+?
Pros:
- Remote I/O Expansion: Allows for easy expansion of I/O capabilities in remote or distributed systems.
- 1-Wire Interface: Enables simple and efficient communication with the host system.
- Open-Drain Outputs: Suitable for driving both logic high and low outputs.
- Low Power: Operates with low power consumption, ideal for energy-efficient designs.
- Small Package: The 6-pin TSOC package is compact, saving board space in designs.
Cons:
- Single Protocol Support: Limited to 1-wire protocol for communication.
- Not Suited for High-Speed Applications: May not be suitable for high-speed I/O requirements.
- Additional Components: May require additional components for protection and conditioning of I/O signals.
Are There Any Equivalents/Alternatives to DS2413P+ for Recommendation?
- The DS2408 from Maxim Integrated is a similar 8-channel I/O expander with additional features.
- Alternatives to the DS2413P+ include the MCP23017 from Microchip Technology and the PCA9555 from Texas Instruments.
