Description for the TPS3617-50

The TPS3617 and TPS3618 are battery-backup supervisors that monitor 5 V supplies. They provide a battery-backup function ideal for applications that require data retention of CMOS RAM during fault conditions. When the voltage at VDD drops below a preset threshold (VIT), the active low push-pull RESET output asserts, and VOUT switches from VDD to VBAT. When VDD rises above the trip threshold, VOUT switches immediately from VBAT to VDD. The RESET output remains low until the delay time (td) expires. During power on, RESET is asserted when the supply voltage (VDD or VBAT) goes higher than 1.1 V.

The PFI and PFO pins are provided if additional voltage monitoring is needed. If the voltage at PFI is less than 1.15 V, the push-pull PFO pin will assert low. When the voltage at PFI exceeds the threshold voltage, PFO will go high.

These devices also feature a watchdog timer pin (WDI) that monitors processor activity and asserts RESET if the the processor is inactive longer than the watchdog timeout period. If the watchdog timer is not used, the WDI pin should be left floating.

The TPS3617 and TPS3618 are available in an 8-pin MSOP package and are characterized for operation over a temperature range of -40°C to +85°C.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships  tube or tray  devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
