Category: Integrated Circuit (IC)
Use: Voltage Supervisor
Characteristics: - Monitors the power supply voltage of a system - Generates a reset signal when the voltage falls below a specified threshold - Prevents erratic behavior or data corruption during power-up and power-down sequences
Package: SOIC (Small Outline Integrated Circuit)
Essence: The TLC7703IDR is a voltage supervisor IC that ensures proper functioning of electronic systems by monitoring the power supply voltage and generating a reset signal when necessary.
Packaging/Quantity: The TLC7703IDR is available in a standard SOIC package. It is typically sold in reels of 2500 units.
The TLC7703IDR has a total of 8 pins:
Advantages: - Ensures reliable system operation during power-up and power-down sequences - Adjustable threshold voltage for flexibility in different applications - Manual reset option for user control - Wide operating temperature range for various environments
Disadvantages: - Limited number of threshold voltage options - Requires external components (resistor divider and capacitor) for proper configuration
The TLC7703IDR operates by comparing the power supply voltage (VIT) with the threshold voltage set by the external resistor divider connected to the TH pin. If the voltage drops below the threshold, the RESET pin goes low, indicating a reset condition. The reset signal remains active for a specified duration determined by the capacitor connected to the CT pin. The MR pin allows for a manual reset by overriding the monitoring function.
The TLC7703IDR is commonly used in various electronic systems where reliable power supply monitoring is crucial. Some application fields include:
These alternative models offer similar voltage monitoring and reset generation features, but may have different specifications and package options.
