Product Overview
Category: Integrated Circuits (ICs)
Use: Voltage Supervisor
Characteristics: - Low Power Consumption - Wide Operating Voltage Range - Adjustable Reset Threshold - Open Drain Output - Small Package Size
Package: SOT-23-5
Essence: The NCP303LSN30T1G is a voltage supervisor IC designed to monitor the power supply voltage and provide a reset signal to the system when the voltage falls below a certain threshold.
Packaging/Quantity: The NCP303LSN30T1G is available in tape and reel packaging, with 3000 units per reel.
Specifications
- Supply Voltage Range: 1.8V to 5.5V
- Reset Threshold Voltage: Adjustable from 2.93V to 3.08V
- Reset Timeout Period: Fixed at 140ms
- Quiescent Current: 1.5µA (typical)
- Operating Temperature Range: -40°C to +85°C
Pin Configuration
The NCP303LSN30T1G has a total of 5 pins:
- GND (Ground): Connected to the ground reference of the system.
- VDD (Supply Voltage): Connected to the positive supply voltage.
- RESET (Reset Output): Open-drain output that goes low when the monitored voltage falls below the threshold.
- MR (Manual Reset): Active-low input used to force a reset regardless of the monitored voltage.
- ADJ (Adjustment): Connected to an external resistor divider network to set the desired reset threshold voltage.
Functional Features
- Voltage Monitoring: The NCP303LSN30T1G continuously monitors the supply voltage and generates a reset signal when it drops below the set threshold.
- Adjustable Threshold: The reset threshold voltage can be adjusted using an external resistor divider network, allowing flexibility in setting the desired voltage level.
- Reset Timeout: Once the reset signal is triggered, it remains active for a fixed timeout period of 140ms before deactivating.
- Manual Reset: The MR pin provides a manual reset option, allowing the system to be reset regardless of the monitored voltage level.
Advantages and Disadvantages
Advantages: - Low power consumption - Wide operating voltage range - Adjustable reset threshold - Small package size
Disadvantages: - Fixed reset timeout period - Limited number of pins for additional functionality
Working Principles
The NCP303LSN30T1G operates by comparing the supply voltage with the adjustable threshold voltage set by the external resistor divider network. When the supply voltage drops below the threshold, the reset output goes low, indicating a power failure or voltage drop. The reset signal remains active for the fixed timeout period before returning to its inactive state. The MR pin allows for a manual reset, overriding the voltage monitoring function.
Detailed Application Field Plans
The NCP303LSN30T1G is commonly used in various applications where reliable voltage monitoring and system reset functionality are required. Some potential application fields include:
- Microcontrollers: Ensuring proper system initialization and preventing data corruption during power fluctuations.
- Battery-Powered Devices: Protecting sensitive circuitry from undervoltage conditions and preserving battery life.
- Industrial Control Systems: Monitoring power supply integrity and providing safe shutdown mechanisms in case of voltage anomalies.
- Automotive Electronics: Preventing damage to critical components by initiating a system reset when the supply voltage falls outside the acceptable range.
Detailed and Complete Alternative Models
- NCP302LSN30T1G: Similar to the NCP303LSN30T1G, but with a fixed reset threshold voltage of 3.0V.
- NCP301LSN30T1G: Voltage supervisor IC with a fixed reset threshold voltage of 3.0V and a longer reset timeout period of 280ms.
- NCP304LSN30T1G: Offers adjustable reset threshold voltage like the NCP303LSN30T1G, but with an extended operating temperature range of -40°C to +125°C.
