产品描述

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.
