Product Overview: TLV803EA26DPWR from Texas Instruments

The TLV803EA26DPWR is a highly reliable voltage supervisor from Texas Instruments, designed to ensure the integrity of your electronic systems. This component is essential for monitoring the power supply voltage levels in microprocessor (µP), microcontroller (MCU), and digital signal processor (DSP) systems. The device asserts a reset signal whenever the VCC supply voltage drops below a preset threshold, ensuring that the system restarts in a known state after experiencing undervoltage conditions.

With a fixed-sense threshold voltage of 2.6V, the TLV803EA26DPWR is tailored for applications that operate within this voltage range and require precise monitoring to avoid data corruption or hardware damage that can be caused by unexpected power dips. The reset output remains active for a minimum of 240 ms after the supply voltage rises above the threshold level, providing ample time for the system to stabilize before resuming operation.

Available in a compact 5-pin SOT-23 package, the TLV803EA26DPWR is designed for space-constrained applications. Despite its small size, it delivers robust performance with a low quiescent current of 9 µA (typical), making it suitable for power-sensitive designs. The device also supports a wide operating temperature range from -40°C to +125°C, ensuring reliable operation in harsh environments.

Key features of the TLV803EA26DPWR include:

• Fixed-sense threshold voltage of 2.6V
• Power-on reset generator with fixed delay time of 240 ms
• Low supply current of 9 µA (typical)
• Manual reset input
• Supply voltage range from 1.2V to 5.5V
• Temperature range from -40°C to +125°C
• 5-pin SOT-23 package

This voltage supervisor is a crucial component for systems that cannot tolerate voltage drops without proper reset mechanisms, such as portable electronics, automotive electronics, industrial control systems, and IoT devices. The TLV803EA26DPWR ensures that these systems maintain their performance and reliability, safeguarding against the potential risks associated with undervoltage events.

For designers and engineers looking for a dependable voltage monitoring solution, the TLV803EA26DPWR from Texas Instruments represents a blend of precision, low power consumption, and compact packaging, making it an excellent choice for a wide range of applications.
