TPS3839K33DQNR - Voltage Supervisor IC by Texas Instruments

The TPS3839K33DQNR is a high-precision voltage supervisor designed by Texas Instruments to monitor system voltages. This device is essential for applications that require a high level of reliability and accuracy in power supply monitoring. It is specifically tailored to ensure that microprocessors, microcontrollers, and other voltage-sensitive components operate within their specified voltage ranges.

The TPS3839K33DQNR operates over a wide supply voltage range and has a low threshold voltage of 3.3V, making it suitable for a variety of low-power applications. The device boasts a very low quiescent current of 1.5 µA, which is particularly beneficial for battery-powered devices where power conservation is critical.

One of the key features of the TPS3839K33DQNR is its ultra-small 1.5-mm x 1.5-mm 6-pin X2SON package, which allows for minimal footprint and easy integration into space-constrained designs. The device also offers a manual reset input, enabling system designers to initiate a system reset independently of the voltage monitoring function.

The TPS3839K33DQNR provides a reset output which remains asserted for a fixed delay time after the monitored voltage has risen above the threshold, ensuring system stability. This feature is crucial for systems that need to stabilize after power-up before commencing normal operation.

With a wide operating temperature range from -40°C to +125°C, the TPS3839K33DQNR is versatile enough to be used in a variety of environmental conditions, making it ideal for industrial, automotive, and consumer electronics applications.

Additional features such as the built-in hysteresis prevent false triggering due to supply noise, and the device's high threshold accuracy (±1%) ensures reliable operation even under fluctuating conditions.

In summary, the TPS3839K33DQNR from Texas Instruments is a robust and reliable solution for voltage supervision in critical systems, offering low power consumption, small package size, and high accuracy in voltage monitoring.
