Supervisory module for monitoring voltage levels

TPS386000RGPT General Description

The TPS386000RGPT is a versatile supply voltage supervisor designed to monitor up to four power rails greater than 0.4 V and one power rail less than 0.4 V, including negative voltages, with exceptional accuracy. With a threshold accuracy of 0.25% (typical), each supervisory circuit can assert a reset signal when the input voltage drops below the programmed threshold. By utilizing external resistors, users can easily program the threshold for each supervisory circuit to meet their specific requirements

Key Features

  • The TPS386000RGPT is a voltage supervisor with integrated power-fail comparator, watchdog timer, and manual reset capability
  • It operates over a wide voltage range (1
  • 6V to 6V) and has a precision voltage monitor with programmable thresholds
  • It also features a small footprint and low-power consumption, making it suitable for a variety of applications
  • Application

    • Ensure system stability
    • Monitor power voltages
    • Generate reset signals
