For programmable logic controller field transmitters or industrial PC designs, microcontroller power rails need voltage monitoring to ensure power within regulation specifications, ensuring system safety.

Benefits:

• Programmable sense-and-reset delay for high-voltage rails
• Manual reset capability to force system resets
• Separate VDD and SENSE pins add redundancy to high-reliability systems
• Functional safety ratings up to Safety Integrity Level (SIL) 3 and SIL 4

In integrated ADAS, monitoring power rails for processors and microcontrollers (MCU) helps prevent brownout from irregular voltage-output conditions. Our portfolio of low-power supervisors help ensure system safety by alerting the MCU during an over- or undervoltage event.

Benefits:

• Multichannel monitoring allows for precise power control on complex designs
• Window detection for systems requiring over- and undervoltage monitoring
• Watchdog feature prevents processing glitches and ensures continuous device functionality
• Support for functional safety requirements up to ASIL D

Motor drives require proper regulation for their power supplies as well as precise sensing for accurate position and torque control. Use our low-current voltage supervisors to monitor core voltage rails and reliable operation without draining power.

Benefits:?

• VIN options up to 65 V with the TPS37 and TPS38
• Multichannel monitoring available
• Adjustable and fixed-sense inputs for high-voltage rails
• Programmable time delay for sequencing flexibility

Energy storage systems rely on voltage supervisors to monitor power rails and assert reset signals when necessary. Our voltage supervisors include low quiescent current (IQ), high precision and exceptional programmability.

Benefits:

• Watchdog timers increase system reliability in the event of an microcontroller malfunction
• Window voltage monitoring for systems requiring over- and undervoltage monitoring
• Minimize power consumption by maintaining ultra-low IQ on up to four channels

Voltage supervisors are imperative when monitoring system health in high-reliability automotive systems where functional safety is paramount. Our voltage supervisors include low quiescent current (IQ), high precision and high programmability.
