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.
