Frequently Asked Questions
What is the reset threshold voltage of the TPS3705-50D?
The TPS3705-50D has a fixed reset threshold voltage of 4.55V, making it specifically designed to monitor 5V supply rails. When the monitored voltage falls below this threshold, the device asserts a reset signal to protect the connected microprocessor or DSP from operating in an undervoltage condition.
Does the TPS3705-50D include a watchdog timer?
Yes, the TPS3705-50D integrates a watchdog timer (WDT) that monitors microprocessor activity and asserts a reset if the processor fails to toggle the watchdog input within the specified timeout period. This provides protection against software lockups and ensures the system can recover automatically.
How many channels does the TPS3705-50D monitor?
The TPS3705-50D is a dual-channel supervisor that monitors two supply voltage rails simultaneously. This allows it to oversee both core and I/O supply voltages of multi-rail systems like FPGAs, microprocessors, and SoCs in a single compact 8-pin SOIC package.
What package does the TPS3705-50D use?
The TPS3705-50D is housed in an 8-pin SOIC (Small Outline Integrated Circuit) plastic epoxy package. It is RoHS compliant and lead-free per JESD-609 e4 classification, suitable for standard surface mount assembly processes used in industrial and consumer electronics manufacturing.
What supply voltages can the TPS3705-50D monitor?
The TPS3705-50D is designed to monitor supply voltages of 2.5V, 3V, 3.3V, and 5V, covering the most common supply rails used in modern digital systems. The 4.55V reset threshold makes it specifically optimized for supervising 5V systems while the dual-channel design supports multi-voltage embedded platforms.
