VS800A Product Overview
Product Category: Integrated Circuits
Use: The VS800A is a voltage supervisor integrated circuit designed to monitor the power supply voltage of a system and provide a reset signal when the voltage drops below a predefined threshold.
Characteristics: The VS800A features a low quiescent current, wide operating voltage range, and adjustable reset threshold. It comes in a small package suitable for space-constrained applications.
Package: The VS800A is available in a compact SOT-23-3 package.
Essence: The essence of the VS800A lies in its ability to ensure the reliable operation of electronic systems by monitoring the power supply voltage and initiating a reset when necessary.
Packaging/Quantity: The VS800A is typically packaged in reels with a quantity of 3000 units per reel.
Specifications
- Operating Voltage Range: 1.2V to 5.5V
- Quiescent Current: 1.5µA
- Reset Threshold Voltage: Adjustable from 1.2V to 4.9V
- Temperature Range: -40°C to 85°C
Detailed Pin Configuration
The VS800A has three pins: 1. VDD: Power supply input 2. GND: Ground 3. RESET: Reset output
Functional Features
The VS800A monitors the power supply voltage and asserts the reset signal when the voltage falls below the user-defined threshold. It incorporates hysteresis to prevent erratic reset operation in noisy environments.
Advantages and Disadvantages
Advantages: - Low quiescent current - Wide operating voltage range - Adjustable reset threshold - Small package size
Disadvantages: - Limited to monitoring single power supply voltage
Working Principles
When the power supply voltage is within the acceptable range, the VS800A remains in a standby state with minimal current consumption. If the voltage drops below the set threshold, the reset output is activated until the voltage rises above the threshold.
Detailed Application Field Plans
The VS800A is commonly used in microcontroller-based systems, battery-powered devices, and other applications where monitoring the power supply voltage is critical for proper operation. It ensures that the system resets in the event of a power supply voltage drop, preventing erratic behavior or data corruption.
Detailed and Complete Alternative Models
Alternative models to the VS800A include the MAX809, ADM811, and TC54 voltage supervisors. These devices offer similar functionality with variations in features such as reset timeout delay and output options.
In conclusion, the VS800A is a versatile voltage supervisor IC with a wide range of applications, offering essential power supply monitoring and reset functionality in a compact and efficient package.
