Frequently Asked Questions
What does the TL7759CPWG4 monitor and what is it used for?
The TL7759CPWG4 is a voltage supervisor IC designed to monitor 5V system power rails. It asserts a RESET output signal whenever the supply voltage falls below a preset threshold, ensuring that connected microcontrollers, FPGAs, and digital logic remain in a defined reset state during power-up, brownout, and power-fail events, preventing erratic system behavior.
Does the TL7759CPWG4 have an adjustable threshold?
No, the TL7759CPWG4 has a fixed (non-adjustable) supervision threshold that is factory-trimmed for 5V system monitoring. This eliminates the need for external resistor dividers or programming components, reducing BOM cost and PCB complexity for designs with a standard 5V VCC rail. For adjustable-threshold applications, Texas Instruments offers other supervisor variants.
What package is the TL7759CPWG4 available in?
The TL7759CPWG4 is packaged in an 8-pin TSSOP (Thin Shrink Small Outline Package), JESD-30 code R-PDSO-G8 with 0.25mm equivalent pitch. This compact surface-mount format enables integration onto small PCBs and is compatible with automated assembly processes, making it ideal for compact embedded systems requiring voltage supervision with minimal board area usage.
What is the typical reset timeout behavior of the TL7759CPWG4?
The TL7759CPWG4 generates a reset pulse that remains asserted for a minimum timeout period after the supply voltage rises above the supervision threshold. This ensures that the power supply has fully stabilized before the microcontroller begins executing code. The timeout period is internally set, eliminating the need for an external timing capacitor as required by older supervisor designs.
