The TPS71247DRCT is a 2.5V microprocessor supervisory circuit used to monitor power supply conditions in microprocessor-based systems. Using a precision voltage reference and comparator circuit, it provides an accurate reset of the system whenever aBrown-out, power-on reset(POR) or watchdog functions are required. This circuit is useful for preventing system data corruption. It features an internal time delay for reset assertion to provide protection against power supply glitches.

The TPS71247DRCT includes a low voltage supply monitoring comparator which allows detection of a power supply drop below a preset level. It also includes an internal watchdog timer which can reset any system timeout errors or operational malfunctions in a microprocessor-based system. It provides four independent reset cycles, an active-low reset signal, and a power-on reset.

The TPS71247DRCT is designed for use in low voltage applications, including microprocessor-based systems that require a reset function. It is designed to be used in conjunction with other components in the system, such as rail-to-rail amplifiers, timers, analog switches, and logic ICs. It can also operate directly from the power rail, eliminating the need for a separate voltage regulator.

The TPS71247DRCT is based on a linear voltage regulator design. This type of voltage regulator is capable of providing a stable voltage output over a wide range of load and temperature conditions, and is suitable for a wide range of low-voltage applications. The TPS71247DRCT includes an adjustable voltage reference circuit and a comparator which can be programmed to detect a power supply drop below a preset level.

The TPS71247DRCT features temperature-compensated internal reference and adjustable RESET/ watchdog threshold voltage. It has good noise immunity, which is essential for reliable operation in harsh, noisy environments. It is designed to minimize power supply ripple, making it suitable for applications where low ripple is important. The device is also designed to minimize output voltage droop under heavy load conditions and to ensure a fast reset response. The TPS71247DRCT is RoHS and Halogen-free compliant.

The TPS71247DRCT is a versatile voltage regulator and reset generator suited for low-voltage applications such as those found in microprocessors and microcontrollers. It provides accuracy and protection in systems where the power supply is subject to transients, glitches, and drops. Its features, including its adjustable reference voltage, low noise immunity and fast reset response, make it suitable for a wide range of applications.
