Advantages and Disadvantages

Advantages

• Low quiescent current consumption helps conserve power in battery-operated systems.
• Wide operating voltage range makes it compatible with various electronic systems.
• Accurate voltage threshold detection ensures reliable system performance.
• Adjustable reset time delay allows customization based on specific system requirements.
• Small package size enables space-saving designs.

Disadvantages

• Lack of integrated features such as watchdog timers or power-on reset functionality may require additional components in certain applications.

Working Principles

The TPS3850H25QDRCRQ1 operates by continuously monitoring the voltage level at the TH pin. When the voltage falls below the threshold set by the TH pin, the RESET pin is activated, generating a reset signal. The reset remains active until the voltage rises above the threshold or a manual reset signal is applied to the MR pin.
