• Quiescent current: 3µA (typical)
• Power-on reset delay time: 20ms (typical)
• Open-drain output configuration

Detailed Pin Configuration

TSM103IDT features a six-pin configuration:

1. GND: Ground connection
2. VDD: Supply voltage input
3. VIN: Voltage input to be monitored
4. RESET: Open-drain reset output
5. TH: Threshold voltage adjustment pin
6. NC: No connection (unused pin)

Functional Features

1. Voltage Monitoring: TSM103IDT monitors the voltage level at the VIN pin and compares it with the threshold voltage set by the TH pin.
2. Reset Output: When the monitored voltage drops below the threshold voltage, the RESET pin becomes active low, indicating a power failure or abnormal voltage condition.
3. Adjustable Threshold: The TH pin allows the user to adjust the threshold voltage according to specific application requirements.
4. Low Power Consumption: With a quiescent current of only 3µA, TSM103IDT minimizes power consumption and extends battery life in portable devices.
5. Wide Operating Temperature Range: This IC can operate reliably in a wide temperature range from -40°C to +125°C, making it suitable for various environments.

Advantages and Disadvantages

Advantages

• Accurate voltage monitoring and supervision
• Adjustable threshold voltage for flexibility
• Low power consumption
• Wide operating temperature range

Disadvantages

• Limited number of pins for additional functionalities
• Requires external components for complete voltage monitoring system implementation

Working Principles

TSM103IDT operates based on a voltage comparator principle. It compares the voltage at the VIN pin with the threshold voltage set by the TH pin. When the monitored voltage falls below the threshold, the RESET pin is activated, indicating a power failure or abnormal voltage condition.

Detailed Application Field Plans

TSM103IDT finds applications in various electronic systems where voltage monitoring and supervision are critical. Some potential application fields include:

1. Power supply units
2. Battery-powered devices
3. Industrial control systems
4. Automotive electronics
5. Home automation systems
