Working Principles

The TLC7701QPWREP is a voltage supervisor IC that monitors the supply voltage and generates a reset signal when it falls below a certain threshold. The threshold voltage can be programmed using the TH pin, allowing flexibility in system design. The delay time for the reset assertion can also be programmed using an external capacitor connected to the CT pin.

When the supply voltage drops below the programmed threshold, the RESET pin goes low, indicating a reset condition. The manual reset input (MR) can be used to force an immediate reset regardless of the monitored voltage level.

The TLC7701QPWREP finds applications in various fields, including:

  1. Automotive: Voltage monitoring in automotive electronics, ensuring proper operation and preventing damage due to low voltage conditions.
  2. Industrial Control Systems: Reset generation in industrial control systems, providing reliable startup and protection against voltage fluctuations.
  3. Power Management: Voltage supervision in power management circuits, enabling safe shutdown or restart during power loss or recovery.
  4. Consumer Electronics: Reset circuitry in consumer electronic devices, maintaining stable operation and protecting sensitive components.
