Details
The DS1259 Battery Manager Chip is a low-cost battery management system for portable and nonvolatile electronic equipment. A battery connected to the battery input pin supplies power to CMOS electronic circuits when primary power is lost through an efficient switch via the VCCO pins. When power is supplied from the battery, the power-fail signal is active to warn electronic reset circuits of the power status. Energy loss during shipping and handling is avoided by pulsing reset, thereby causing the battery to be isolated from other elements in the circuits.FEATURES■ Facilitates uninterruptible power■ Uses battery only when primary VCC is not available■ Low forward voltage drop■ Power fail signal interrupts processor or write protects memory■ Consumes less than 100 nA of battery current■ Low battery warning signal■ Battery can be electrically disconnected upon command■ Battery will automatically reconnect when VCC is applied■ Mates directly with DS1212 Nonvolatile Controller x 16 Chip to back up 16 RAMs■ Optional 16-pin SOIC surface-mount package

FAQs
What is DS1259+?
The DS1259+ is a high-precision, real-time clock (RTC) module with integrated temperature compensation, designed by Maxim Integrated. It is ideal for applications requiring accurate timekeeping, such as industrial automation, data logging, and electronic instrumentation.
How Does DS1259+ Work?
The DS1259+ utilizes a combination of a highly accurate crystal oscillator, temperature sensor, and compensation circuitry to maintain precise timekeeping over a wide temperature range. It features nonvolatile time storage, automatic backup, and a serial interface for easy integration with microcontrollers and systems.
How Many Pins does DS1259+ have and What are the Functions of the Pinout Configuration?
The DS1259+ is housed in a 20-pin SOIC (Small Outline Integrated Circuit) package. The pinout configuration includes:
- VCC: Power supply pin.
- GND: Ground pin.
- OSC1, OSC2: Connections to the external crystal oscillator.
- SDA, SCL: Serial data and serial clock pins for I2C communication.
- N.C.: No connection pin.
- VBAT: Battery input pin for backup power.
- IRQ: Interrupt output pin.
- TS: Temperature sensor output pin.
- RESET: Reset input pin.
What are the Pros and Cons of DS1259+?
Pros:
- High Accuracy: Provides precise timekeeping with integrated temperature compensation.
- Nonvolatile Storage: Retains time information even in the absence of power.
- Serial Interface: Allows for easy communication and configuration with microcontrollers and systems.
- Wide Temperature Range: Maintains accuracy over a wide operating temperature range.
- Integrated Features: Includes temperature sensor, backup power input, and interrupt output for enhanced functionality.
Cons:
- Package Size: The 20-pin SOIC package may be relatively larger for space-constrained designs.
- Complexity: Requires understanding of I2C communication and configuration for integration into systems.
- Additional Components: May require an external crystal and backup battery for complete operation.
Are There Any Equivalents/Alternatives to DS1259+ for Recommendation?
- The DS3231 from Maxim Integrated is a similar high-precision RTC module with additional alarm and temperature-compensated crystal oscillator (TCXO).
- Alternatives to the DS1259+ include the MCP7940N from Microchip Technology and the RX8900CE from Epson.
