The Texas Instruments TPS3617-50DGKR is a single-channel battery backup supervisor IC housed in an 8-VSSOP package. This device is designed to monitor a 4.55V supply and provide a battery backup switchover function, crucial for maintaining RAM retention during power failures.
Key electrical characteristics include a typical threshold voltage of 4.55V with 2% accuracy, an active-low push-pull reset output, and a fixed 100ms reset delay. It also incorporates a watchdog timer with an 800ms timeout and a power-fail input/output feature. The supervisor operates over a temperature range of -40°C to 85°C.
With a low supply current of 40µA (max) and battery supply current of 100nA (max), the TPS3617-50DGKR is suitable for portable and battery-powered applications. Its surface mountable 8-VSSOP package makes it convenient for integration into compact designs. Applications include fax machines, set-top boxes, advanced voice mail systems, and automotive systems requiring reliable power monitoring and reset functions.
