Product details

Battery backup supervisor — the 1.6 V rail watchdog

The TPS3610U18PWR: When the primary supply fails, it switches the load to a backup battery, keeping the downstream SRAM or RTC alive. The active-low, push-pull reset output drives directly into the enable pin of a memory chip or microcontroller without needing an external pull-up resistor.

Obsolete — plan for a replacement now

Any stock you find is new-old-stock or surplus inventory already on the shelf. For a new design, do not specify this part; look for a current-generation battery backup supervisor with a 1.6 V threshold in a similar package.

14-TSSOP footprint and temperature grade

Housed in a 14-TSSOP package with a 0.173-inch (4.40 mm) body width, this part uses a standard TSSOP-14 land pattern — the same footprint used by many TI supervisory ICs in this family.
