Overview of Texas Instruments TPS3836E18DBVR

The Texas Instruments TPS3836E18DBVR is a high-precision voltage supervisor designed to monitor the voltage levels in digital systems and ensure that the system voltage remains within specified thresholds. This device is particularly suitable for applications that require a reliable and accurate power-on reset (POR) signal, or for systems that need to be reset when a voltage drops below a predetermined level.

Key Features

• Voltage Threshold: The TPS3836E18DBVR has a preset threshold voltage of 1.8V, making it ideal for low-voltage applications that run on 1.8V power rails.
• High Accuracy: With a tight threshold accuracy of ±2%, this device ensures precise monitoring and reliable operation.
• Low Power Consumption: The device is designed for power-sensitive applications, consuming a very low quiescent current of typically 9 µA.
• Reset Time Delay: It features a fixed delay time of 200 ms (typical) before asserting the reset signal, providing ample time for the system to stabilize.
• Supply Voltage Range: The TPS3836E18DBVR operates over a wide supply voltage range from 1.1V to 5.5V, accommodating a variety of power sources.
• Temperature Range: This device is operational over an extended temperature range from -40°C to +85°C, suitable for industrial environments.
• Small Package: Housed in a compact SOT-23-3 package, it is space-efficient and easy to integrate into space-constrained designs.
• Open-Drain Output: The reset output is an open-drain configuration, allowing for flexible interfacing with other logic levels or for connecting multiple supervisors in a wired-OR configuration.

Applications

The TPS3836E18DBVR is versatile and can be used in a wide range of applications, including:

• Battery-powered equipment
• Portable electronics
• Microprocessor/microcontroller systems
• Industrial controls
• Handheld devices

With its precision voltage monitoring and low power consumption, the TPS3836E18DBVR from Texas Instruments is a reliable solution for systems that require consistent and accurate voltage supervision to protect against undervoltage conditions.
