TPS3836E18DBVTG4 Voltage Supervisor by Texas Instruments

The TPS3836E18DBVTG4 is a high-precision voltage supervisor from Texas Instruments, designed to maintain system integrity by monitoring the supply voltage of digital systems. This device is particularly suitable for battery-powered electronics where maintaining the correct operation voltage is critical for system reliability.

With a fixed-sense threshold voltage of 1.8V, the TPS3836E18DBVTG4 ensures that the systems it monitors do not operate under conditions that could lead to unpredictable behavior. The voltage threshold accuracy is an impressive ±1.5%, which is ideal for applications requiring a high degree of precision.

One of the key features of this supervisor IC is its ultra-low power consumption. The quiescent current is typically only 9µA, which is advantageous for prolonging battery life in portable devices. This makes the TPS3836E18DBVTG4 an excellent choice for mobile phones, PDAs, and other handheld equipment.

The device comes in a compact 5-pin SOT-23 package, which is suitable for space-constrained applications. It is also characterized for operation over a temperature range of –40°C to +85°C, making it robust enough for use in a wide range of environments.

The TPS3836E18DBVTG4 features a manual reset input that allows the user to initiate a system reset. It also has a reset timeout period of 200ms, ensuring that the system has sufficient time to stabilize before normal operation resumes. The reset output is active low and is of the push-pull type, which does not require an external pull-up resistor, simplifying the design and saving board space.

Designed with the needs of modern electronics in mind, the TPS3836E18DBVTG4 from Texas Instruments is a reliable solution for voltage supervision in critical applications. Its precision, low power consumption, and compact form factor make it an essential component for designers looking to enhance system stability and extend battery life.

For detailed specifications and application guidance, engineers should consult the datasheet and Texas Instruments' technical resources to ensure proper integration into their designs.
