It asserts an active-low reset signal when the monitored voltage drops below the 3.3V threshold, and releases it after an adjustable timeout period once the supply returns within tolerance. The open-drain output can be pulled up to a different voltage rail, making it straightforward to interface with 1.8V or 5V logic domains.
Surface-mount assembly with a standard reflow profile handles the VDFN package.
The reset timeout is adjustable and selectable via an external capacitor. The datasheet provides the capacitor value versus timeout period relationship — this lets you tailor the delay to the power-up sequence of the downstream processor.
The TPS3852H33DRBR and TPS3852H33DRBT share the same base product number and electrical specifications. The suffix difference indicates packaging and reel quantity — confirm the specific tape-and-reel variant matches your assembly feeder requirements before substituting.
