TPS389033GQDSERQ1

TPS389033GQDSERQ1 is part of the Texas Instruments (TI) family of PMIC (Power Management Integrated Circuit) Supervisors. This supervisor is for automotive and telecom applications, as well as a wide range of battery powered devices.

The TPS389033GQDSERQ1 acts as a reset generator. It monitors the input voltage and ensures that it keeps within the pre-defined safe operating level. If the voltage exceeds or falls below that safe level, the TPS389033GQDSERQ1 will reset the system to prevent it from entering an unstable mode that could potentially damage the system.

The TPS389033GQDSERQ1 uses a comparator and reference voltage to compare the input voltage to a target voltage window. When the voltage falls out of the target window, an input reset signal is generated and a reset signal (RESET) is issued. This reset signal is used to reset the microcontroller or can be routed to any other desired device. The reset event also starts an internal timer, which keeps the reset signal active for the duration of a reset time-out period.

The TPS389033GQDSERQ1 also offers a brown-out detect (BOD) feature which monitors the voltage level of the power supply input, and issues a pulse signal when the voltage drops below the programmed BOD threshold. This signal can then be used to take some pre-defined action in order to protect the system.

The TPS389033GQDSERQ1 can be programmed with different reset/BOD thresholds and reset time-out periods. These settings are made using external digital control pins or using 3-wire digital serial interface or I2C digital interface. These features, combined with the high accuracy of the TPS389033GQDSERQ1 make it ideal for many automotive and telecom applications where voltage levels are critical.

In conclusion, the TPS389033GQDSERQ1 is a highly reliable PMIC Supervisors for many applications. Its integrated voltage monitoring and time-out functions offer great protection for any system, all in a small, low-power package.
