Frequently Asked Questions

At what voltage does TL7757CLPE3 assert a reset signal?

The TL7757CLPE3 asserts its reset output when the monitored supply voltage falls below the fixed 4.55 V reset threshold, ensuring the connected microprocessor or microcontroller is held in reset during under-voltage conditions to prevent erratic operation.

How many supply rails can TL7757CLPE3 monitor simultaneously, and what package does it use?

The TL7757CLPE3 is a single-channel voltage supervisor capable of monitoring 1 supply rail at a time. It is housed in a compact 3-pin SOT-23 package (JESD-30 code O-PBCY-W3), occupying minimal PCB area for space-constrained designs.

Can TL7757CLPE3 replace a discrete resistor-divider reset circuit for 5 V microcontroller boards?

Yes, the TL7757CLPE3 eliminates the need for external resistors by integrating a precision 4.55 V threshold, simplifying BOM to 1 component and improving threshold accuracy compared to typical ±5% resistor divider approaches, reducing design complexity on 5 V microcontroller boards.

Is TL7757CLPE3 suitable for automotive or industrial temperature ranges?

The TL7757CLPE3 is rated for the commercial temperature range. For industrial or automotive applications requiring operation from -40°C to +125°C, engineers should evaluate the TL7757 family variants specified for extended temperature grades before committing to this suffix.
