The Texas Instruments TLC77331ID is a high-performance, low-power voltage supervisor designed to monitor the supply voltage of microprocessors (μPs), microcontrollers (MCUs), and other voltage-sensitive systems. This precision voltage supervisor ensures that the systems it monitors operate optimally within their voltage thresholds, safeguarding them from unpredictable conditions that could lead to system failures or data corruption.

The TLC77331ID is equipped with a fixed-sense threshold voltage of 3.1V, making it particularly suitable for 3.3V systems. When the monitored supply voltage falls below the threshold, the device triggers a reset signal that remains active until the supply voltage returns to acceptable levels, plus a certain time delay to ensure system stability. This reset signal ensures that the system has enough time to return to a stable operating condition before resuming normal operation.

Key Features:

• Precision Voltage Monitoring: Fixed threshold accuracy at 3.1V suitable for 3.3V powered systems.
• Low Power Consumption: Ideal for power-sensitive applications, it draws minimal current.
• Programmable Reset Delay: The reset time delay can be set by an external capacitor, which provides design flexibility.
• Push-Pull Reset Output: The device features a push-pull reset output, negating the need for external pull-up resistors.
• Temperature Range: Operates over a wide temperature range, making it suitable for industrial applications.
• Supply Voltage Range: Supports a wide range of supply voltages, enhancing compatibility with various system designs.

The TLC77331ID comes in an 8-pin SOIC package, offering a compact footprint for space-constrained applications. Its robust design and manufacturing from Texas Instruments ensure high reliability and performance consistency, which is critical for maintaining system integrity in harsh environments and demanding applications.

Whether used in computing systems, portable/battery-powered devices, or complex industrial equipment, the TLC77331ID voltage supervisor from Texas Instruments is an essential component for maintaining system health and preventing costly downtime.
