description

The TPS3600 family of supervisory circuits monitor and control processor activity. In case of power-fail or

brownout conditions, the backup-battery switchover function of TPS3600 allows to run a low-power processor

and its peripherals from the installed backup battery without asserting a reset beforehand.

During power on, RESET is asserted when the supply voltage (VDD or VBAT) becomes higher than Vres.

Thereafter, the supply voltage supervisor monitors VOUT and keeps RESET output active as long as VOUT

remains below the threshold voltage (VIT). An internal timer delays the return of the output to the inactive state

(high) to ensure proper system reset. This delay timer starts its time-out, after VOUT has risen above the

threshold voltage (VIT). In case of a brownout or power failure of both supply sources, a voltage drop below the

threshold voltage (VIT) get detected and the output becomes active (low) again.

The product spectrum is designed for supply voltages of 2 V, 2.5 V, 3.3 V, and 5 V. The circuits are available

in a 14-pin TSSOP package. They are characterized for operation over a temperature range of −40°C to 85°C.
