The TLC7701QPWRG4 from Texas Instruments is a low-power supervisor integrated circuit. It is ideal for a wide range of supervisory applications, offering robust and reliable monitoring of system power rails. The TLC7701QPWRG4 supports both active-high and active-low restart into applications, providing flexibility for system design. It includes an 8-bit reset timer and low-voltage detection with an active resettable RC circuit that has a wide range of voltage threshold levels, plus the voltage range can be adjusted by the user. The device offers a low hysterisis voltage, which helps reduce false reset due to noise in systems.

The TLC7701QPWRG4 is designed to monitor the VCCP, VPWR and VDD power rails. It has an active-high shutdown output and active-low reset output. This device also features a two-level reset timer to prevent false reset due to noise transients and enable a complete power-on reset system. The voltage range can be adjusted with the R1 and R2 external resistors. The device includes an integrated reverse current path clamp that helps protect the VCCP, VPWR and VDD power rails.

The TLC7701QPWRG4 is designed to provide the most reliable system monitoring and protection. It has a wide operating voltage range of 2.7V to 5.5V and comes in the 8-pin, lead-free SOIC package. The device is ideally suited for embedded systems that require low power, such as Internet of Things (IoT) applications. It also offers high levels of radiation and ESD hardening, making it suitable for harsh environments as well as military and aerospace applications.

The TLC7701QPWRG4 works by monitoring the power rails for under-voltage conditions. When the device detects an under-voltage condition, it will issue a reset or a shutdown of the system, depending on the user settings. The device also has the ability to detect a low-voltage condition at the power rail and issue an active-high reset. With the adjustable voltage range, the user can control the low-voltage thresholds, which helps reduce false reset due to noise in systems. The two-level reset timer also helps prevent a false reset due to noise transients.

The TLC7701QPWRG4 is a robust and reliable power supervisor IC and is suitable for a wide range of applications. It features a wide operating voltage range, adjustable reset thresholds, a low-hysteresis voltage, and a two-level reset timer, making it an ideal choice for embedded systems that require low power and reliable system protection. The device also offers high levels of radiation and ESD hardening, making it suitable for harsh environments and advanced applications.
