BATTERY-BACKUP SUPERVISORS FOR LOW-POWER PROCESSORS
SLVS336 – DECEMBER 2000

POST OFFICE BOX 655303
DALLAS, TEXAS 75265
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 (V
DD
or V
BAT
) becomes higher than 1.1 V.
Thereafter, the supply voltage supervisor monitors V
OUT
and keeps RESET output active as long as V
OUT
remains below the threshold voltage (V
IT
). 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 V
OUT
has risen above the
threshold voltage (V
IT
). In case of a brownout or power failure of both supply sources, a voltage drop below the
threshold voltage (V
IT
) get detected and the output becomes active (low) again.
The product spectrum is designed for supply voltages of 2 V, 3.3 V, and 5 V. The circuits are available in a 14-pin
TSSOP package. The TPS3600 devices are characterized for operation over a temperature range of –40
°
C to
85
°
C.
