Product Overview: TPS3805H33DCKR

The TPS3805H33DCKR is a high-precision voltage supervisor designed and manufactured by Texas Instruments, a leader in semiconductor solutions. This device is tailored to monitor the system voltage and maintain the integrity of the power supply in digital systems. It is particularly suitable for applications that require a strict control over power supply fluctuations and where the reliability of operation is paramount.

Constructed with a fixed-sense threshold voltage of 3.3V, the TPS3805H33DCKR ensures that systems remain within operational voltage limits. This voltage supervisor is capable of providing a reset signal to the microcontroller in the event of the system voltage dropping below the threshold, thus preventing system failures and data corruption.

The TPS3805H33DCKR comes in a compact SC-70 package with 5 pins, making it an ideal choice for space-constrained applications. Despite its small size, it does not compromise on performance, featuring a low quiescent current of only 9 µA, making it an energy-efficient solution for portable and battery-powered devices.

Key Features:

• Fixed voltage detection (3.3V)
• Low quiescent current (9 µA)
• Manual reset input
• Power-on reset generator with adjustable delay time
• Supply voltage range from 1.1V to 5.5V
• Open-drain RESET output
• Temperature range: -40°C to 85°C
• 5-pin SC-70 package

The device also includes a manual reset input, allowing for a system reset to be triggered manually as required. Additionally, the power-on reset generator comes with an adjustable delay time, providing flexibility for different system requirements. The open-drain RESET output ensures compatibility with various logic levels, and the wide operating temperature range makes the TPS3805H33DCKR suitable for industrial and automotive environments.

With its precision voltage monitoring and low power consumption, the TPS3805H33DCKR from Texas Instruments is an excellent choice for designers looking to enhance system reliability and stability in applications such as portable electronics, computers, servers, and other critical digital systems.
