Use

This IC is commonly used for voltage monitoring and reset functions in electronic devices.

Characteristics

• Voltage monitoring: The DS1233DZ-15+ monitors the supply voltage of a device and provides a reset signal when the voltage falls below a certain threshold.
• Reset function: It ensures that the device is properly reset after a power-on or brownout event.
• Low power consumption: The IC operates with low power requirements, making it suitable for battery-powered applications.
• Wide operating voltage range: It can operate within a wide voltage range, typically from 2.7V to 5.5V.

Package and Quantity

The DS1233DZ-15+ is available in a small outline package (SOP) with eight pins. It is typically sold in reels containing a specified quantity of units.

Specifications

• Supply voltage range: 2.7V to 5.5V
• Reset threshold voltage: 4.63V
• Reset timeout period: 15ms
• Operating temperature range: -40°C to +85°C
• Package type: SOP-8

Pin Configuration

The DS1233DZ-15+ has eight pins arranged as follows:

```

---

| | --| VCC GND |-- Pin 1: Ground (GND) --| RST OUT |-- Pin 2: Output (OUT) --| MR IN |-- Pin 3: Input (IN) --| GND RST |-- Pin 4: Reset (RST) |___________| ```

Functional Features

• Voltage monitoring: The DS1233DZ-15+ continuously monitors the supply voltage and compares it to the preset threshold.
• Reset signal generation: When the voltage falls below the threshold, the IC generates a reset signal to ensure proper device operation.
• Manual reset input: The MR pin allows for manual resetting of the device.
• Power-on reset delay: The IC provides a delay before generating the reset signal upon power-up to allow stable voltage levels.

Advantages and Disadvantages

Advantages

• Reliable voltage monitoring and reset functionality.
• Low power consumption.
• Wide operating voltage range.
• Compact package size.

Disadvantages

• Limited reset timeout period (15ms).
• Requires external components for specific applications.

Working Principles

The DS1233DZ-15+ operates by comparing the supply voltage with the preset threshold. If the voltage drops below the threshold, the IC triggers a reset signal. This ensures that the device is properly reset and prevents erratic behavior due to low voltage conditions. The IC also includes a manual reset input for additional control.

Application Field Plans

The DS1233DZ-15+ finds applications in various electronic devices where voltage monitoring and reliable reset functionality are crucial. Some potential application fields include: 1. Microcontrollers and microprocessors 2. Embedded systems 3. Power management circuits 4. Industrial automation systems 5. Consumer electronics

Alternative Models

• DS1233DZ-10+: Similar to DS1233DZ-15+, but with a different reset timeout period (10ms).
• DS1233DZ-20+: Similar to DS1233DZ-15+, but with a different reset timeout period (20ms).
• DS1233DZ-25+: Similar to DS1233DZ-15+, but with a different reset timeout period (25ms).

These alternative models provide flexibility in choosing the appropriate reset timeout period based on specific application requirements.

In conclusion, the DS1233DZ-15+ is a versatile integrated circuit that offers reliable voltage monitoring and reset functionality. Its low power consumption, wide operating voltage range, and compact package make it suitable for various electronic devices. However, its limited reset timeout period and reliance on external components may be considered as disadvantages in certain applications.
