The TPS3838E18DBVR is a precision, ultra-low Quiescent current (QC) voltage supervisor device. It is equipped with an on-chip voltage reference, making it suitable for many applications, including battery-powered systems, supervision of external supplies, reset generation, and real-time clock monitoring.

The TPS3838E18DBVR voltage supervisor provides a single, active-low reset output in the event of an over voltage or under voltage of the system power channels, or when the output drops below the factory-programmed reset threshold. The device can optionally be configured with a voltage hysteresis to eliminate false reset generation as a result of power surges.

The TPS3838E18DBVR supervisor operates with an input voltages from 2.5 V to 5.5 V and is available in a variety of packages. It is designed for applications that need high accuracy, low power consumption and fast response time. The device is available with either fixed reset threshold values or adjustable ones. The device can also be configured with a separate high threshold and hysteresis, providing high stability when monitoring low-frequency clock signals. Additionally, the TPS3838E18DBVR can be programmable with a dual pair of reset threshold values.

The TPS3838E18DBVR is a highly accurate voltage supervisor, with a high accuracy of 0.9 %VREF. Its ultra low-quiescent current consumption and fast response time (2 ms typical) make it ideal for applications where power consumption and speed are important factors. Additionally, the active low open-drain Reset output is robust against static and dynamic noise, offering improved performance in heavy industrial or noisy environments.

The TPS3838E18DBVR is designed for use in a wide variety of applications, including system monitoring, monitoring of external supplies and activity, reset generation, and real-time clock monitoring. It is ideal for battery-powered applications where low power consumption and accurate control of the system voltage is required. Additionally, the TPS3838E18DBVR is designed for use in high reliability critical systems such as automotive and medical applications.

The TPS3838E18DBVR is based on a voltage sensing architecture, making it particularly well suited for monitoring of the system input voltage and reset generation when the voltage drops below the programmed reset threshold. The triggering voltage level is maintained by the on-chip voltage reference, and can be set to either fixed values or an adjustable value. Additionally, the device can be configured to provide a reset hysteresis, allowing it to robustly eliminate false reset evictions due to spikes in the system power.

The TPS3838E18DBVR is an ideal device for monitoring and resetting a wide variety of system-level voltages, ranging from 2.5V to 5.5V. Its high accuracy ensures a reliable output, while its ultra-low QC and fast response time make it suitable for applications where power consumption and speed are important. Additionally, the active low open-drain reset offers improved noise immunity over traditional reset solutions. As such, the TPS338E18DBVR is an ideal choice for many PMIC-Supervisor applications.
