Product Overview: Texas Instruments TLV803EA22DBZR

The TLV803EA22DBZR is a high-precision voltage supervisor designed to maintain system integrity by monitoring the supply voltage of digital systems. Manufactured by Texas Instruments, a leader in semiconductor solutions, this compact device is an essential component for a wide range of applications, including microprocessor, microcontroller, and FPGA systems that require stringent voltage regulation.

Key Features

• Supply Voltage Monitoring: The TLV803EA22DBZR keeps a vigilant eye on the system's supply voltage, ensuring it doesn't fall below a critical threshold, which is preset to 2.2V. This helps to prevent system failures and data corruption caused by inadequate power supply levels.
• Reset Output: Upon detecting an undervoltage condition, it asserts a reset signal, holding the system in a reset state for a minimum of 140ms after the supply voltage has risen above the threshold, ensuring the system has sufficient time to stabilize.
• Low Power Consumption: With a quiescent current of just 3.3 µA, the device is optimized for battery-powered and low-power applications, where power conservation is critical.
• Small Form Factor: Housed in a tiny 3-pin SOT-23 package, the TLV803EA22DBZR is designed for space-constrained applications, providing a reliable solution without occupying much board space.

Applications

The TLV803EA22DBZR is versatile and can be used in a variety of applications, including:

• Portable and battery-powered electronics
