DESCRIPTION

The TPS3613-01 supervisory circuit monitors and controls

processor activity by providing backup-battery switchover

for data retention of CMOS RAM.

During power-on, reset (RESET and RESET) is asserted

when the supply voltage (VDD or VBAT) becomes higher

than 1.1 V.

Thereafter, the supply voltage supervisor monitors VDD at

the SENSE pin through external feedback resistors and

keeps reset active as long as SENSE remains below the

threshold voltage, VIT.

An internal timer delays the release of the reset state to

ensure proper system reset. The delay time starts after

SENSE rises above the threshold voltage, VIT.

When SENSE drops below VIT, reset becomes active

again.

The TPS3613-01 is available in a 10-pin MSOP package

and is characterized for operation over a temperature

range of −40°C to +85°C.
