Product details

What this supervisor does for your 3.3V rail

The TPS3852H33DRBT is a single-channel voltage supervisor that monitors a 3.3V supply rail and asserts a reset signal when the voltage drops below the threshold. It is the part you reach for when a microcontroller, FPGA, or SoC needs a clean, glitch-free reset during power-up or a brownout event. The reset output is Active Low and open-drain, so it can be wire-ORed with other reset sources or pulled up to a different voltage than the monitored rail. The reset timeout is adjustable with an external capacitor, giving you control over how long the processor stays in reset after the supply stabilises.

Package and temperature range for the application

The 8-VDFN exposed pad package (Supplier Device Package 8-SON) is a surface-mount footprint with a 3x3 mm body.

Sourcing posture and lifecycle

Because the lifecycle is active, you can order this part against a BOM line without worrying about a looming obsolescence.

Frequently asked questions

Can TPS3852H33DRBT replace TPS3852H33 in an existing design?

The TPS3852H33DRBT shares the same base product number TPS3852 and the same 3.3V threshold. The 'DRBT' suffix indicates the 8-SON (3x3) package and Tape & Reel packaging. If the original TPS3852H33 was in a different package, confirm the footprint compatibility before substituting. The electrical specifications for the 3.3V threshold and reset behaviour are identical across the family.

Is TPS3852H33DRBT compatible with a push-pull reset output?

No — the TPS3852H33DRBT has an open-drain output, not push-pull. An open-drain output requires an external pull-up resistor to the desired reset voltage rail. If your design expects a push-pull output, you would need a different supervisor or add a pull-up resistor and accept the logic-level translation.
