Package

TSM1011AIST is available in a small surface-mount package, typically a SOT-23-5 or similar.

Essence

The essence of TSM1011AIST lies in its ability to accurately monitor and supervise voltage levels in electronic systems, ensuring proper functioning and preventing damage due to overvoltage or undervoltage conditions.

Packaging/Quantity

Typically, TSM1011AIST is sold in reels or tubes containing a specified quantity of units, such as 2500 pieces per reel.

Specifications

• Supply voltage range: 2.8V to 18V
• Operating temperature range: -40°C to +125°C
• Output type: Active low or active high
• Threshold voltage accuracy: ±1.5%
• Quiescent current: 10µA (typical)

Detailed Pin Configuration

TSM1011AIST features a standard pin configuration with five pins:

1. GND (Ground): Connected to the ground reference of the system.
2. VDD (Supply Voltage): Connected to the positive supply voltage of the system.
3. VIN (Voltage Input): Connected to the voltage source being monitored.
4. SET (Threshold Set): Connected to an external resistor to set the desired threshold voltage.
5. OUT (Output): Provides the monitored voltage status as an active low or active high signal.

Functional Features

• Overvoltage and undervoltage detection: TSM1011AIST can detect when the monitored voltage exceeds or falls below the set threshold.
• Adjustable threshold voltage: The SET pin allows users to set the desired threshold voltage according to their specific requirements.
• Fast response time: TSM1011AIST provides quick detection and response to voltage variations, ensuring timely protection of the system.

Advantages and Disadvantages

Advantages

• Wide operating voltage range allows for versatile applications.
• Small package size enables space-saving designs.
• High accuracy ensures reliable voltage monitoring.
• Low quiescent current consumption minimizes power consumption in standby mode.

Disadvantages

• Limited number of output options (active low or active high).
• Lack of built-in hysteresis may require additional external circuitry for noise immunity.

Working Principles

TSM1011AIST operates based on a voltage comparator principle. The input voltage (VIN) is compared with the threshold voltage set by an external resistor connected to the SET pin. When the VIN crosses the threshold, the output (OUT) changes state, indicating an overvoltage or undervoltage condition.

Detailed Application Field Plans

TSM1011AIST finds applications in various fields, including but not limited to:

1. Power supply units: Ensuring stable voltage levels in power supplies.
2. Battery management systems: Monitoring battery voltage to prevent overcharging or deep discharge.
3. Industrial automation: Protecting sensitive electronic components from voltage fluctuations.
4. Automotive electronics: Safeguarding automotive systems from voltage anomalies.
5. Consumer electronics: Preventing damage to devices due to voltage irregularities.
