Product details

Three-rail supervisor for mixed-voltage boards

The reset timeout is a minimum of 140ms, giving the system power supplies time to settle before the processor starts executing code. This part is rated for the industrial temperature range of -40°C to 85°C, making it suitable for factory automation, motor drives, and outdoor telecom equipment where the ambient temperature can swing.

Threshold voltages and reset timing

The push-pull output eliminates the need for an external pull-up resistor, saving board space and reducing BOM count. Both active-high and active-low outputs are available, so the same part can interface with processors that require either polarity of reset.

Package and mounting

Housed in an 8-SOIC package with a 3.90mm body width, the TPS3307-33DR is a surface-mount part that fits standard SOIC-8 footprints. Cut Tape quantities are also available for prototyping or low-volume builds.

Frequently asked questions

What are the threshold voltages for TPS3307-33DR?

The TPS3307-33DR monitors three thresholds: 2.93V, 4.55V, and one adjustable input that can be set with an external resistor divider.

Can TPS3307-33DR replace TPS3307-33D?

The TPS3307-33DR is the Tape & Reel variant of the base TPS3307-33D. Electrical specifications are identical; the only difference is packaging format. The -DR suffix indicates Tape & Reel, while the -D suffix typically indicates tube or other packaging. Verify the package type matches your assembly process.

Is the TPS3307-33DR output active high or active low?

The TPS3307-33DR provides both active-high and active-low reset outputs, giving flexibility to interface with processors that require either polarity.
