Key Features
- 65V maximum sense voltage enables direct supervision of high-voltage industrial and automotive rails without an external voltage divider, simplifying system protection circuits
- Integrated overvoltage and undervoltage detection with programmable reset delay and watchdog timer consolidates multi-function supply monitoring into a single 14-pin SOIC
- Ultra-low quiescent current minimizes standby power in battery-backed and energy-harvesting systems that need always-on voltage supervision with adjustable OV/UV thresholds
Applications
The TPS3760A012DYYR is designed for high-voltage industrial power supplies, motor drive controllers, and 48V automotive battery management systems that require simultaneous overvoltage and undervoltage protection with a watchdog timer to detect software lockups. Its 65V sense input range and adjustable threshold make it suitable for monitoring wide-input-range DC-DC converters, solar charge controllers, and telecom rectifiers where supply rail excursions above nominal demand an immediate system reset. Embedded safety-critical platforms including industrial robots and EV charging stations benefit from its integrated manual reset input and programmable delay, which prevent nuisance trips during normal load transients.

Frequently Asked Questions
What is the maximum sense voltage of TPS3760A012DYYR and how does it simplify 48V automotive rail supervision?
The TPS3760A012DYYR can sense supply voltages up to 65V directly at its input pin, covering the 48V nominal automotive battery rail and its transient peaks without an external resistor voltage divider on the sense node. This reduces the component count by at least 2 resistors per channel and eliminates the tolerance stack-up that external dividers introduce into the threshold accuracy, keeping the OV/UV trip points within the adjustable range set by the internal reference.
How does the integrated watchdog timer in TPS3760A012DYYR protect against software lockups in an embedded motor controller?
The watchdog timer monitors a periodic kick signal from the microcontroller firmware; if the host fails to toggle the WDI pin within the programmed window—typically tens of milliseconds to several seconds depending on external timing components—the TPS3760A012DYYR asserts a reset output to restart the CPU. In a motor controller this prevents a locked-up processor from commanding a motor to run indefinitely at full current, which could cause mechanical damage or thermal shutdown in under 10 seconds at rated load.
When should a designer choose TPS3760A012DYYR over a simpler single-threshold UV supervisor for a 24V industrial power supply?
A single-threshold UV supervisor only asserts reset when the supply falls below one fixed level, leaving overvoltage faults undetected. TPS3760A012DYYR adds OV detection, a watchdog, manual reset input, and programmable delay in one 14-pin package—essential for 24V industrial supplies where load rejection can spike the rail 30% to 50% above nominal for milliseconds, potentially exceeding component absolute maximum ratings if not flagged. Its adjustable thresholds allow the OV trip to be set at 28V and UV at 20V, covering the full IEC 61131 allowable range for industrial 24V bus systems.
