Product Overview: TPS3839G18DBZR by Texas Instruments

The TPS3839G18DBZR is a high-precision voltage detector designed by Texas Instruments (TI) for monitoring power supply voltages in electronic devices. This tiny, low-power integrated circuit (IC) is a critical component for systems that require reliable voltage supervision to ensure proper operation and to protect against undesired under-voltage conditions.

Key Features

• Voltage Threshold: The device features a fixed-sense threshold voltage of 1.8V, which makes it suitable for applications that operate around this voltage level.
• Low Current Consumption: With a typical supply current of only 0.75 µA, the TPS3839G18DBZR is an ideal choice for battery-powered and low-power applications.
• High Accuracy: It offers high threshold accuracy (±1%) which is crucial for applications where precise voltage monitoring is necessary.
• Fast Response Time: The device provides a fast response to under-voltage events, ensuring timely system protection or recovery.
• Manual Reset: A manual reset input is available, allowing external control over the reset function.
• Power-On Reset Generator: The IC includes a built-in power-on reset generator which ensures that the system microcontroller or processor starts up in a known state after power-up.
• Temperature Range: It operates over a wide temperature range from -40°C to +125°C, accommodating various environmental conditions.
