• Guaranteed reset assertion down to VCC = 1V

Package and Quantity

The DS1232LPS-2+ is available in a small outline transistor (SOT) package, specifically SOT-23-5. It is sold in quantities of [insert quantity].

Specifications

• Operating temperature range: -40°C to +85°C
• Reset timeout period: adjustable from 140ms to 1120ms
• Reset threshold voltage: 2.93V (typical)
• Reset pulse width: 250ms (minimum)

Pin Configuration

The DS1232LPS-2+ has a total of five pins arranged as follows:

```

---

| | --| RST | --| GND | --| MR | --| VCC | --|_______| ```

1. RST: Active-low reset output
2. GND: Ground reference
3. MR: Manual reset input
4. VCC: Power supply voltage input

Functional Features

• Power-on reset generation: The DS1232LPS-2+ ensures that the reset output remains active until the power supply voltage reaches the specified threshold level.
• Manual reset input: The manual reset (MR) pin allows for an external signal to force a reset condition, overriding the power-on reset.
• Adjustable timeout period: The reset timeout period can be adjusted using external components, allowing flexibility in defining the duration of the reset signal.
• Low power consumption: The IC operates with minimal power consumption, making it suitable for battery-powered applications.

Advantages and Disadvantages

Advantages

• Reliable power-on reset functionality
• Small package size enables space-saving designs
• Wide operating voltage range accommodates various power supply configurations
• Low power consumption prolongs battery life in portable devices

Disadvantages

• Lack of built-in protection features against voltage spikes or transients
• Limited availability of alternative models with similar specifications

Working Principles

The DS1232LPS-2+ monitors the power supply voltage and generates a reset signal based on predefined thresholds. When the power supply voltage falls below the specified threshold, the reset output is activated, indicating a reset condition. The reset signal remains active until the power supply voltage rises above the threshold level or a manual reset signal is applied.

Application Field Plans

The DS1232LPS-2+ finds application in various electronic systems that require reliable power-on reset functionality. Some potential application fields include: 1. Microcontrollers and microprocessors 2. Embedded systems 3. Industrial automation 4. Consumer electronics 5. Medical devices
