DS1233A-10

Product Overview

Category

DS1233A-10 belongs to the category of integrated circuits (ICs).

Use

The DS1233A-10 IC is primarily used for power supply monitoring and reset functions in electronic devices.

Characteristics

• Power supply monitoring: The DS1233A-10 monitors the voltage level of the power supply and provides a reset signal when the voltage falls below a certain threshold.
• Reset function: It generates a reset signal to ensure proper initialization of the device when the power supply voltage returns to normal levels.
• Low power consumption: The IC operates with low power consumption, making it suitable for battery-powered devices.
• Wide operating voltage range: It can operate within a wide voltage range, typically from 2.7V to 5.5V.
• Small package size: The DS1233A-10 is available in a compact package, making it suitable for space-constrained applications.

Package and Quantity

The DS1233A-10 is packaged in a small outline integrated circuit (SOIC) package. It is commonly available in reels or tubes containing a quantity of 250 or 300 units per package.

Specifications

• Supply Voltage Range: 2.7V to 5.5V
• Operating Temperature Range: -40°C to +85°C
• Reset Threshold Voltage: 4.63V (typical)
• Reset Timeout Period: 10ms (typical)
• Quiescent Current: 20µA (typical)

Pin Configuration

The DS1233A-10 IC has the following pin configuration:

____ VCC --| |-- GND RESET --| |-- OUT GND --| |-- MR ----

• VCC: Power supply voltage input
• RESET: Reset output signal
• GND: Ground reference
• OUT: Power supply monitoring output
• MR: Manual reset input

Functional Features

1. Power Supply Monitoring: The DS1233A-10 continuously monitors the power supply voltage and detects any drop below the reset threshold.
2. Reset Signal Generation: When the power supply voltage falls below the reset threshold, the IC generates a reset signal to ensure proper device initialization.
3. Manual Reset Capability: The MR pin allows for manual reset activation, overriding the automatic reset function.
4. Reset Timeout: The IC includes a reset timeout feature that ensures the reset signal is not held indefinitely in case of a power supply glitch.

Advantages and Disadvantages

Advantages

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

Disadvantages

• Limited availability of alternative models with similar specifications
• May require additional external components for specific applications

Working Principles

The DS1233A-10 operates by continuously monitoring the power supply voltage using an internal voltage comparator. When the voltage drops below the reset threshold, the IC triggers the reset signal. The reset signal remains active until the power supply voltage returns to normal levels or until the reset timeout period elapses. The MR pin allows for manual reset activation, providing flexibility in certain scenarios.

Application Field Plans

The DS1233A-10 finds application in various electronic devices where reliable power supply monitoring and reset functions are essential. Some potential application fields include:

1. Microcontrollers and microprocessors
2. Embedded systems
3. Industrial automation equipment
4. Consumer electronics
5. Medical devices
6. Automotive electronics

Alternative Models

While the DS1233A-10 is a widely used IC for power supply monitoring and reset functions, there are alternative models available from different manufacturers. Some notable alternatives include:

1. MAX1233A
2. LTC1233
3. MCP1233

These alternative models offer similar functionality and can be considered as substitutes for the DS1233A-10 in specific applications.

In conclusion, the DS1233A-10 is a versatile integrated circuit that provides reliable power supply monitoring and reset functions. Its low power consumption, wide operating voltage range, and compact package make it suitable for various electronic devices across different industries. While alternative models exist, the DS1233A-10 remains a popular choice due to its performance and availability.
